Design and analysis of cooperative communication schemes based upon modeling and simulation exist in large quantities in the research literature. Despite this fact, there have been relatively few efforts directed toward implementing and experimentally evaluating such schemes. Cooperative protocols have many components that make them challenging to implement in real-world radio architectures, and their...
Cooperative communication has been intensively considered for general wireless and sensor networks. However, it has been almost untouched in space-time-frequency coded multi-band OFDM ultra-wideband (STFC MB-OFDM UWB) systems. This paper thus proposes two cross-layer designs for cooperative communication, namely simple cooperative communication scheme (SCCS) and advanced cooperative communication...
In current cooperative communication schemes, to achieve cooperative diversity, synchronization between terminals is usually assumed, which may not be practical. In this paper, shift-orthogonal space-time block codes (SOSTBC) for relay networks without the assumption of synchronization is described. Then based on the set of zero correlation zone (ZCZ) sequence, the definitions of zero cross-correlation...
To exploit the cooperative diversity for wireless relay networks, signal space diversity can be combined with practical cooperative communication schemes. In this paper, we investigate cooperative modulation schemes at the symbol level based on fully decoding received signals at the bit level. We propose a novel decode-remodulate-and-forward (D-ReM-F) cooperative modulation scheme that works well...
In current cooperative communication schemes, to achieve cooperative diversity, synchronization between terminals is usually assumed, which may not be practical since each terminal has its own local oscillator. In this paper, based on the stack construction proposed by Hammons and El Gamal, we first construct a family of space-time trellis codes for BPSK modulation scheme that is characterized to...
