Abstract :
We analyze the performance of a fixed-point turbo decoder using two sliding window algorithms for the 3GPP standard. We show that the bit and frame error rate performance of the sliding window scheme strongly depends on the guard window size. Simulation results also indicate that small guard window sizes can significantly decrease the iteration gain for large frames
