Software simulation of LDPC codes and performance analysis

In this paper we will analyze the influence of using Low Density Parity Check LDPC codes in different channels environment. The performances of LDPC codes are estimated in several scenarios. The simulation software gives us the possibilities to choose between different communications channels according to the encoding matrix used. Also we can adjust a number of parameters, thing that help to find the optimal solution depending on the decoding error rate or Bit Error Ratio (BER). Optimal combinations between parameters, the encoding matrix and structures design are obtained, related to required performance or Signal Noise Ratio (SNR) ranges. The sets of parameters and criteria introduced are discussed as the simulation results, also.
