Clearly, making use of user cooperation transmission technique in a multi-hop wireless network improves its performance in terms of transmission reliability and gives birth to multi-hop wireless relay networks. In this paper, we investigate and evaluate the Bit Error Rate (BER) of multi-hop wireless relay networks employing distributed Space-Time Block Coding (STBC) at many relays' levels. One relays'...
In the existing literatures on cooperative relay system, the coding scheme adopts the conventional fixed-rate code (traditional code). This paper first studies the rateless code, Raptor code, to cooperative wireless cellular system. In particular, we study the efficiency, reliability, and robustness of cooperative communication in a wireless cellular downlink environment by employing a new scheme...
