Resource Allocation for Two-Relay Networks with Mixed Relaying Protocol in Railway Environments

چکیده
In this paper, we analyze the effect of resource allocation in two-relay networks with mixed relaying protocol. We assume that two relay nodes exist between the source node and destination node, and one relay node adopts decode-and-forward (DF) relaying protocol and the other one uses amplify-andforward (AF) relaying protocol. Differential modulation scheme is applied for all cases to bypass channel estimation. We investigate the performance of the proposed system by considering the location of relay nodes, i.e., co-located and various location scenarios, depending on the existence of direct link.

متن کاملResource Allocation of Two-relay Networks with Partially Differential Modulation
Relay networks enhance the system performance by creating cooperative diversity gain and extend communication range by relaying the received signal to other devices. In this paper, the performance of two-relay networks is analyzed by adopting decode-andforward (DF) relaying protocol. The signaling scheme uses partially differential modulation which applies coherent modulation in source-relays l...
