Efficient Resource Allocation with Flexible Channel Cooperation in OFDMA Cognitive Radio Networks
Recently, a cooperative paradigm for single-channel cognitive radio networks has been advocated, where primary users can leverage secondary users to relay their traffic. However, i...

Iterative Detection and Decoding for Hard-Decision Forwarding Aided Cooperative Spatial Multiplexing
— In this paper, 1 the optimal decoding strategy for cooperative spatial multiplexing (CSM) aided systems is derived. In CSM systems, the multiple relay stations (RSs), which com...
