Relay communication network is a technique to obtain spatial diversity by using one or more relay terminals in order to improve the transmission performance. Amplifty-and-forward (AF) and decode-and-forward (DF) are two kinds of fixed relaying protocols and widely researched now. In this paper the performance of AF and DF in terms of the outage probability and the symbol error rate (SER) is analysed...
As a new transmission technique, cooperative diversity means that multiple terminals share their resources to form a virtual antenna array so that the space diversity can be realized. In this paper, a new strategy called hybrid amplify or decode-and-forward (HADF) is presented, which is based on some basic strategies of cooperative communication, such as amplify-and-forward (AF) and decode-and-forward...
