Abstract:
In this paper the decoding performance of a Turbo-Code and a LDPC-Code are compared. Both exhibit a binary blocklength of 504 and a coderate of 0.5. After an explanation of the several channel code’s construction methods the results of the simulations are depicted in terms of the Bit Error Rate (BER). For a channel model the Additive White Gaussian Noise Channel (AWGNC) has been used. The decoding was done with the iterative Belief Propagation (BP)-decoding algorithm. If carefully constructed, the LDPC-Code is clearly favorable over the applied Turbo-Code.
