Asymmetric turbo coded modulation with transmit and receive antenna diversity [articol]

Abstract

This paper analyses the performances of turbo coded modulation with antenna diversity at transmission and reception, considering asymmetric turbo codes. We studied the cases when the component convolutional codes have memory 2 and 3, respectively, and their generator polynomials are both primitive and non-primitive. Simulations were performed to study these cases, considering both quasi-static and block fading, and the bit error rate (BER) and the frame error rate (FER) performances of asymmetric turbo coded modulation were evaluated. Based on this analysis, we note that primitive polynomials lead to better performances for FER, whereas the non-primitive ones lead to slightly improvements of BER in low SNR range.
