In this paper, a reduced complexity Log-MAP algorithm based on a non-recursive approximation of the max∗ operator is presented and studied for turbo trellis-coded modulation (TTCM) systems. In the algorithm, denoted as AvN Log-MAP, the max∗ operation is generalized and performed on n ≥ 2 arguments. The approximation is derived from the Jensen inequality.(More)
One of the most important parts of the vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication is reliable transmission that allows the achievement of good throughput in the system. In terms of high system throughput, two issues need to be taken into consideration. First, accurate estimation that is crucial for the successful application(More)

A reduced-complexity modified decoding algorithm for turbo trellis-coded modulation (TTCM) is proposed and evaluated in terms of complexity and bit error rate (BER) performance in an additive white Gaussian noise (AWGN) channel. A novel method is derived from the Chebyshev inequality. In this approach, the max* operation is performed on n≥2(More)
