The two user multiple-input multiple-output (MIMO) broadcast channel is studied in which the channel from one of the receivers is known instantaneously and perfectly at the transmitter, whereas the channel from the other receiver is known in a delayed manner. The degrees of freedom (DoF) region of the two-user (M; N1; N2) - MIMO broadcast channel under this model is completely characterized. The scheme...
In FD-AWGN relay channel, the source sends the superposition of many capacity-achieving codewords. The relay decodes them using successive interference cancellation (SIC) and sends the superposition of the same codewords multiplied by random dither sequences and with a new power distribution among the codewords. The destination node decodes all code-words by removing the dithering and then applying...
