... the performance here is similar to the scheme in [7] where a naive AF protocol was considered. A similar trend holds for the performance in the UL in Figure 5. Recall that the decode and forward ... signals to the relays, forming an interference channel; and in the second phase, the relays forward the signals to the base stations, which cooperate to perform joint processing to form a multip...

... different bit values in b p , that is, d 1 = j − 1. It should be noted that since the Hamming distance for all the bits associated with p j = g 1 has been computed, the p j element should be removed for ... matrix for projection. This matrix can be controlled by the application provider, and therefore the users do not need to carry the matrix (or equivalently a key for matrix generat...
