Performance evaluation and comparison between LDPC and turbo coded MC-CDMA

Abstract EN

This work presents a comparison between the Convolutional Encoding CE, Parallel Turbo code and Low density Parity Check (LDPC) coding schemes with a Multi User Single Output MUSO Multi-Carrier Code Division Multiple Access (MC-CDMA) system over multipath fading channels.

The decoding technique used in the simulation was iterative decoding since it gives maximum efficiency at higher iterations.

Modulation schemes used is Quadrature Amplitude Modulation QAM.

An 8 pilot carrier were used to compensate channel effect with Least Square Estimation method.

The channel model used is Long Term Evolution (LTE) channel with Technical Specification TS 25.101v2.10 and 5 MHz bandwidth band width including the channels of indoor to outdoor / pedestrian channel and Vehicular channel.

The results showed that the performance of the proposed system was better when the LDPC was used as a coding technique.
