| Abstract: | In this paper we consider downlink transmission in a multiuserMultiple Input Multiple Output (MIMO) OFDM systems, where eachbase station transmits multiple data streams to its mobiles. Wefind the optimal transmit and receive weight vectors, usingdistributed schemes, to maximize total data rate for each user. Weconsider two scenarios, where in one the total power per user andin the other total power per subcarrier is fixed. In each case wepropose iterative algorithms to maximize the allocated rate peruser. We will discuss the convergence of our schemes and comparetheir performance with that of the previous works. | ||
