In cooperative communication single antenna mobiles can share their antennas to improve communication links and increase channel capacity. Node cooperation generates a virtual multiple-antenna system which attains close to optimal multiple input multiple output (MIMO) gains. At the same time, power line communication (PLC) offers stable high data rate for indoor communications, and also benefits from...
The problem of multiuser multiplexing with a MIMO sub system for each individual user is considered. We demonstrate that the capacity performance of the null space based spatial multiplexing schemes can be improved with iterative power allocation within the iterative design process. We considered water-filling based local and global power allocation and demonstrate that both schemes outperform the...
In this paper, we propose a generalized greedy (G-greedy) algorithm based on zero-forcing beamforming (ZFBF) for the multiple-input multiple-output (MIMO) broadcast channel. This algorithm serves as a general mathematical framework that includes a number of existing greedy user selection methods as its realizations. As previous results only give the scaling law of the sum rate of dirty paper coding...
