Title
Two Network Coding Diversity Enhancement Schemes For Wireless Relay Systems
Abstract
In this letter, two new network coding (NC) diversity enhancement schemes are introduced for wireless relay systems. Conventional diversity enhancement approaches for relay systems suffer from error propagation at each relay and exhibit second order diversity performance. In the proposed schemes, when a relay experiences a decoding failure, the relay makes a request to have the source transmit the NC frames to the destination in its time slot. Due to this operation, the proposed schemes prevent error propagation and achieve near third order diversity performance. The proposed schemes are compared to conventional schemes based on the derived mathematical error bounds and simulation performance, both of which demonstrate the superiority of the proposed schemes.
