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.
