Performance Analysis of LTE Systems with Convolutional Encoding over Fading Channels

Abstract: The advanced wireless systems feature Long-Term Evolution (LTE) is one of the wide band standards. This paper delivers detailed performance evaluations of LTE systems which implement 2X2 and 4X4 Multiple-Input Multiple- Output (MIMO) configurations through Rayleigh fading channels. The system uses convolutional encoder and viterbi decoder to achieve better system performance. The proposed test method evaluates system performance through the implementation of convolutional encoding and decoding under multiple modulation types QPSK, 16-QAM and 64-QAM. The simulation results presents how the error control coding method benefits the performance in severe fading wireless environment.
