Abstract

A scheme for exploiting cooperation in satellite receivers is proposed. The cooperation takes place through a capacity-constrained link, and we assume that a relay node quantizes its received signal and sends it to the destination node. We demonstrate its effectiveness with three different schemes on satellite channels with high-order APSK modulations. The first two schemes employ equidistant quantization levels and the proposed receivers are respectively based on Minimum Mean Square Error (MMSE) filtering and on a simple modification of the BCJR transition probabilities. The third scheme works with a quantized version of LLRs. We show that the latter has higher gains when the number of quantization bits is lower than the number... (More)

A scheme for exploiting cooperation in satellite receivers is proposed. The cooperation takes place through a capacity-constrained link, and we assume that a relay node quantizes its received signal and sends it to the destination node. We demonstrate its effectiveness with three different schemes on satellite channels with high-order APSK modulations. The first two schemes employ equidistant quantization levels and the proposed receivers are respectively based on Minimum Mean Square Error (MMSE) filtering and on a simple modification of the BCJR transition probabilities. The third scheme works with a quantized version of LLRs. We show that the latter has higher gains when the number of quantization bits is lower than the number necessary to represent all the modulation symbols and that in this case there is a simple approach to cluster together symbols and design a quantization scheme.
