Differential diversity-embedding space-time block coding for 2 and 4 transmit antennas
Diversity-Embedding Space-Time Block Coding (DE-STBC), introduced in [1], enables Unequal Error Protection (UEP) using multiple transmit antennas. Even though these codes do not re...

How much feedback overhead is required for base station cooperative transmission to outperform non-cooperative transmission?
Coherent base station (BS) cooperative transmission provides high spectrum efficiency for cellular systems when channel state information (CSI) is perfectly known at the BSs. For...
