Abstract

We consider the performance of low-density parity-check (LDPC) codes, turbo codes and convolutional codes over the binary-input AWGN channel with at Rayleigh fading. LDPC and turbo codes are capacity-approaching codes for long codewords. For short and medium codewords we seek to determine if they still outperform the industry-standard memory-6, rate-1/2 convolutional code. For a fixed SNR, the probability of error for the codes of interest are plotted as a function of codelength. We find that for very short codewords, the convolutional code performs best.
