MIMO Downlink Weighted Sum Rate Maximization with Power Constraints per Antenna Groups
Abstract— We consider a single-cell multiple-input multipleoutput (MIMO) downlink channel where linear transmission and reception strategy is employed. The base station (BS) tran...

An iterative power allocation algorithm in OFDM system based on power relaxation
Abstract— We present an efficient algorithm for power allocation and bit loading in multi-user OFDM system. We starts with the close-form optimum power solution based on ideal c...
