Optimization of Path Selection in MIMO

Abstract

Multi-hop communication is the best way for improving the coverage area with reduced transmission power.This paper can easily found a path selection based on multi-hop decode and forward (DF) cooperative system. Then it is said to be a simple parallel multi-hop paths based cooperative communication system. Recently, cooperative communication have attracted significant attention to tackle the limitations imposed by multiple-input-multiple-output (MIMO) technology. To eliminate these limitations and increase spectral efficiency, Compress-and-Forward(CF) technique was proposed. In many known examples where compress-and-forward(CF) for relay networks is capacity achieving, it is only trivially so, i.e., it falls back to hashing without quantization.A potentially better strategy is to decode as much as possible and to compress the residual information, i.e., a combination of decode-and-forward (DF) and CF.
