JSCC-UFMC and Large MIMO Technology for High Data Rate Wireless Communication

Abstract

To reduce the system complexity, cost, and overall processing time, the adoption of joint source-channel coding (JSCC) has been found to be popular. Among several options, universal filtered multi-carrier (UFMC) is regarded as the dominant contender and alternative to orthogonal frequency division multiplexing (OFDM) for upcoming wireless mobile communication networks. UFMC provides increased spectral efficiency, less peak to average power ratio (PAPR), and lower bit error rate (BER) with the removal of the cyclic prefix (CP) and grouping of subcarriers. Multiple-input and multiple-output (MIMO) technology is known to improve the capacity and throughput significantly of wireless systems. In this paper, the authors analyze the performance of UFMC techniques with Kaiser filter and Dolph-Chebyshev filter combined with JSCC in 32x32 large MIMO set-up, which provides better PAPR, power spectral density (PSD), less BER with increased channel capacity. The experimental aspects have been discussed and the results are derived using simulation mimicking near real-life situations.
