... this article, we propose a novel scheduling algo- rithm with an adaptive, utility-based scheduling metric for the multiuser MIMO uplink, together with the sup- port for SDMA. The study is limited ... ficients for each user follow the Rayleigh distri- bution. As there are no recommendations for multiuser MIMO channel models, we defined a MIMO channel for each user an...

... Rayleigh fading for each path. The system parameters are N t = M = 100 for all cases; for PAM-16, K = 16, N r = 13; for PAM-8, K = 6, N r = 6; for PAM-4, K = 8 with N r = 9, and for PAM-2, K = ... (i) for higher-order modulations we group B data streams together which will form a 2 B -ary PAM sym- bol. This is done as follows: the antenna sequence partitions s k,m for the data...

... method does not work for solving the GMVIP (1.1). There- fore, it is worth studying other implementable methods for solving the problem (1.1). Algorithms that can be applied for solving the problem ... [0, 1) . We first describe a new projective splitting algorithm for t he GMVIP (1.1), and then give some preliminary results on the algorithm. Algorithm 3.1. Step 0. (Initiation) S...
