احترام آدمیت
اس کائنات ِرنگ و بو میں ہر چیز اپنی شناخت اور پہچان رکھتی ہے، اپنے وجود کے اظہار کے لیے اس کی کوئی نہ کوئی شناخت ہے سورج کی شناخت یہ ہے کہ وہ مشرق سے نکلتا ہے اور مغرب میں غروب ہو جاتا ہے، ستاروں کی شناخت یہ ہے کہ وہ رات کو آسمان پر درخشاں ہوتے ہیں۔ پہاڑوں کی شناخت اور پہچان یہ ہے کہ دور سے دکھائی دیتے ہیں اور بلندو بالا ہوتے ہیں۔ اسی طرح پھول کی پہچان ہے کہ وہ خوشبوفراہم کرتا ہے اور اپنے اردگرد کے ماحول کو معطر اور خوشبودار رکھتا ہے۔ اسی طرح مسلمان کی بھی ایک پہچان ہے وہ یہ کہ اس کے ہاتھ اور زبان سے دیگر مسلمان محفوظ رہتے ہیں۔ وہ کسی کو گزند نہیں پہنچا تا کسی کو تکلیف پہنچانا اس کو ناگوار گزرتا ہے۔ کسی کی پریشانی وہ اپنی پریشانی سمجھتا ہے۔ تو بس اس بات کا قائل ہوتا ہے کہ آدمی اور انسان کا احترام کیا جائے اور اس کے حفظ مراتب کا خیال رکھا جائے۔ قرآنِ پاک میں بھی انسان کے ساتھ حسنِ سلوک اور رواداری کی تلقین آئی ہے۔ ارشادِ باری تعالیٰ ہے:
’’لوگوں کے ساتھ احسن طریقے سے گفتگو کر یں، حسن سلوک سے پیش آئیں ‘‘
اسلام کی جملہ تعلیمات احترامِ آدمیت کی تلقین کرتی ہیں نماز ایک ایسی عبادت ہے جس کو ہم دن میں پانچ مرتبہ ادا کرتے ہیں۔ اور اس میں بھی حکم ہے کہ جب مسجد میں نماز ادا کرنے کے لیے کوئی آئے خواہ وُہ لباس فاخرہ میں ملبوس ہو، خواہ وہ صاف مگر سادہ لباس زیب تن کئے ہوئے ہو۔ خواہ اس کا قد بڑا ہو، د بلا پتلا ہو یا لحیم شہیم ہو وہاں سب برابر ہیں۔ اور ایک ہی صف میں کھڑے ہوں گے امیر وغریب اور سرخ سفید...
Dealings of the Holy Prophet (S.A.W) with non-Muslim show that Islam is the religion of peace, brotherhood, religious tolerance, independence and humanity. Before the spread of Islam the conversations and dealings of the Holy Prophet with non-Muslims forced them to call him Al-Sadiq and Al-Ameen. Sympathy and tolerance in clandestine and public preaching, the style of letters to non-Muslim empires, the dialogues with non-Muslim delegations in Madani era, the orders given for the safety of their wealth, belongings and their life, the tolerance, forgiveness and prayers for the enemies, the good behavior with the non-Muslim prisoners, even when Muslims got dominance over non-Muslims at the time of the conquest of Makkah, the common pardon given by Holy Prophet (S.A.W) are the true example that Islam preaches peace. The attitude of Sahaba-e-Karam (R.A) and the liberty of rights given to Non-Muslims by them- no religion and no community of the World can give this example. The people responsible for maintaining the peace of the world and brotherhood should see how Muslims are treated all over the world? Muslims had given to non-Muslim permission to practice their religious festivities freely and even to wear any type of clothes. The ban of Hijab in France, the punishment of innocent Dr. Afia Siddiqui, the Egyptian pregnant woman (Marwa Sharbeney) had been mercilessly assassinated and her husband injured by knives in the court of Germany because of Hijab, the discussions going on to restrict the domes of Mosques and Adhan (Call to prayer) in Switzerland, the insult of the Holy Quran by Pope Terry John, of Florida, the disrespect of Holy Prophet (S.A.W) etc are the questions awaiting answers from West and United Nation. Islam promotes of peace, equality and religious freedom. It also invites non-Muslims to come and sit on a platform and discuss these problems for the sake of worldly peace to end the religious hatred and to form true peace in the world.
Fifth Generation (5G) is considered to be the future advancements in wireless technology. The ever increasing number of smart network devices may obsolete latest 4G technology for handling bandwidth allocation to a large number of smart devices. To meet with this challenging need, for rapid and efficient data transfer over such devices, requires next generation mobile technology. 5G technology is anticipated to offer appropriate solutions to such issues. High data rates can be achieved by using 5G, however, to make such futuristic technology realistic, is a real challenge. This challenging goal can be achieved by efficient utilization of the bandwidth in allocated spectrum. In this context, Cognitive Radio (CR), is an intelligent radio which has inherent adaptive procedures. It reuses the frequency when primary user is absent and works on principle of dynamic frequency allocation. CR is one of the key enabling technology for 5G networks which allows nodes to evaluate and manage underused licensed channels. It has brought benefits to a CR based 5G cellular networks which include ability to adapt dynamicity of a network, deals with the spectrum scarcity issue and operates in heterogeneous environment. It also provides intelligent solutions and self-governing capabilities to assist 5G key functions especially in smart beamforming. Another promising enabling technology of 5G is massive multiple-input multipleoutput (MIMO). Due to its attributes such as increased spectral and energy efficiency, it is envisaged as a potential technology for fifth generation (5G) wireless communication networks. As already mentioned that radio spectrum has become a scarce resource in wireless communications, hence imposes excessive cost on the high data rate transmission. Several linear and non linear detection techniques such as Zero-Forcing (ZF), Minimum Mean Square Error (MMSE), and Vertical Bell-Labs Layered Space Time (VBLAST) have been introduced. The purpose of such schemes is to mitigate the signal detection problems which are based on trade-offs between the bit error rate (BER) performance and computational complexities. The challenge in the design of massive- MIMO systems is developing less complex and efficient detection algorithms. The problem in building a receiver for massive-MIMO is to de-correlate the spatial signatures on the receiver antenna array. In this thesis, firstly, 5G technology, its challenges and proposed solutions are presented. Secondly, CR based 5G technology is investigated with the view to explore both technologies jointly and to present a comprehensive overview which will invigorate new research initiatives in this exciting field. Thirdly, a novel algorithm viz: Hybrid n-Bit Heuristic Assisted-VBLAST (HHAV) to perform an optimum decoding for massive-MIMO, is proposed. This structure is simulated in dynamic Rayleigh fading channel. One of the latest decoding algorithm viz: approximate message passing (AMP) is also evaluated with two threshold functions which include AMP with ternary distribution (AMPT) and AMP with Gaussian distribution (AMPG). Numerical results confirm that proposed HHAV algorithm performs significantly well as compared to the performances of aforementioned detection systems introduced in recent years. Finally, a novel 6G intelligent IOT paradigm is presented to optimize communication channels and process big data intelligently. The enabling technologies and AI based 6G air interface architecture, based on our proposed paradigm are also discussed. The results are evaluated through simulation by comparing our proposed paradigm with 5G-IOT and 5G intelligent IOT. In relation to our proposed concept, simulation results confirm that the performance in terms of effective utilization of channels is significantly improved.
