LDPC performance in IEEE802.16e and Telemetry systems

In this thesis there is a detailed note on LDPC codes history and types. There are many standards such as IEEE802.16e, IEEE802.11ad, IEEE802.11n, Telemetry systems etc. use LDPC codec for their implementation. There are simulation models for the physical layers of IEEE802.16e and Telemetry system are developed. Both the simulated models have been analyzed as per the standard speci ed rates and code sizes. For IEEE802.16e the codeword length 'N' varies from 576 to 2304 with six different data rates. In this standard physical layer implementation different modulation schemes are considered such as QPSK, 16-QAM and 64-QAM. Telemetry system is been analyzed for message block lengths of 1024, 4096 with three different rates specified. In this standard physical layer implementation the modulation schemes considered are QPSK and 16-QAM. The decoder used for both standards is Bit- ipping algorithm
