Abstract
Pattern Division Multiple Access (PDMA) is a novel non-orthogonal multiple access scheme proposed to meet up the diverse demands on high capacity and large number of connections in the fifth generation (5G) wireless networks. PDMA uses the characteristic pattern to define the sparse mapping from data to a group of resources, and the sparsity of the pattern gives impacts on the capacity performance and detection complexity. The present thesis emphasizes greatly to develop a simulation model for the 5G compatible downlink Pattern Division Multiple Access (PDMA) scheme implemented wireless communication system. The simulated system incorporates a modern channel coding ((3, 2) SPC) and different low order digital modulation (4-QAM, QPSK and DQPSK) schemes. With implementation of G [2,3] PDMA pattern matrix for three users and considering total transmitted power of 40 Watt, 50%, 30% and 20% of total transmitted power have been assigned to first, second and third users and additionally phase shifting factors have been applied in power scaled transmitted signals of second and third users to resolve ambiguity in individual data separation. On consideration of both synthetically generated binary data stream and color image transmission in AWGN and Rayleigh fading channel, it is observable from MATLAB based simulation study that the ((3, 2) SPC) channel encoded simulated system is very much robust and effective in retrieving transmitted data. The impact of applicability of 2-D median image filtering technique in processing of three different identically sized color images and enhancement of image quality has clearly been observed. This thesis elucidates the benefits of multi-user data transmission in power domain.
