Abstract :
To address transmission problems encountered in WLAN environments, we propose a multi-user MIMO SDMA system based on the theory of convex optimization. With each user´s BER as the cost function, we compute transmit and receive matrices to achieve optimal system performance. The proposed algorithm is assessed by simulations and is compared with conventional methods
