Turbo and convolutional codes assisted Space Time Block Code-Spatial Modulation

Abstract

Two coding techniques are adopted in this paper to improve the performance of Space Time Block Codes-Spatial Modulation (STBC-SM). The two adopted coding techniques are the turbo-coding technique and the convolutional-coding technique over block fading channel. The signals used in the two coded systems are assumed to be modulated using BPSK and QPSK. The MATLAB simulation results show that at a BER of 10.5, the turbo-coded and convolutional-coded systems can provide about 3-4.5 dB and 2.7-3.8 dB coding gains respectively compared with the uncoded system.

Modelling and Performance Analysis of Massive MIMO-OFDM Wireless System with Turbo Encoding

“…The initial applications were in the military communications. Weinstein and Ebert applied the discrete Fourier transform (DFT) to parallel data transmission system as part of the modulation and demodulation process [3]. In the 1980s, OFDM has been studied for high speed modems and for digital mobile communications [3].…”

In 1990s, OFDM has found its applications in wideband data communications over mobile radio FM channels, wireless LAN, wireless multimedia communication, high-bit-rate digital subscriber lines (HDSL), asymmetric digital subscriber lines (ADSL), digital audio broadcasting (DAB), digital video broadcasting (DVB).…”
