This paper investigates the application of advanced forward error correction techniques mainly: Turbo code, Low-Density Parity Checks (LDPC) code, and Raptor code for wireless communication systems in the low power regime (LPR). These codes are under consideration for many recent technologies. Different code parameters such as code rate and several decoding iterations are used to show their effect on the performance of digital systems. Simulation results showed that the Raptor code is performed better than Turbo code and LDPC code over binary input additive white Gaussian noise (BI_AWGN), for the same coding rate and the number of decoding iterations. Considering bit error rate (BER) performance, Raptor code with rate1/2 and 1/3 provided better performance than Turbo and LDPC for the SNR up to -5dB for the AWGN channel. Finally, in comparison with Turbo and LDPC, Raptor code shows better performance for a large number of decoding iterations and low coding rates.
