In the downlink transmission scenario. power allocation and beamforming design at the transmitter are essential when using multiple antenna arrays. This paper considers a multiple input–multiple output broadcast channel to maximize the weighted sum-rate under the total power constraint. The classical weighted minimum mean-square error (WMMSE) algorithm can obtain suboptimal sol... https://safeersappliancers.shop/product-category/bosch-gud15aff0g-integrated-undercounter-freezer/
