Comparison of BCH Code Performance in LTE-Advanced Cooperative System in Suburban, Urban and Rural Environment Based on WINNER II Channel Model

Multi-path fading is a severe issue that causes fluctuations in the amplitudes of the received signals. For combating this issue, several researchers have used cooperative communication in the Long-Term Evolution (LTE)-advanced system. To further decrease the degradative effects of transmitted signals, various error correction techniques can be used to recover the erroneous components, especially when the channel has been deep fading. The paper investigates the general performance of the Convolutional Codes (CC) in the LTE-advanced cooperative system and compare it with the Bose-Chaudhuri-Hocquenghem (BCH) codes. The comparison is based on WINNER II project as the channel model between the nodes in the two coding processes. To validate the advantages of BCH code, the process were tested on three different environments; a suburban macro-cell, urban macro-cell, and the rural micro-cell with prior study to understand the appropriate relay height in every environment. Path loss models for each environment were derived and proposed as part of the proposed simulation framework. Conducted simulation studies based on bit error rate and direct connection showed that the use of the CC and th
