Surrogate-Enhanced Fractional Programming for MIMO Device-to-Device Interference Networks
Zihan Jiao, Xinping Yi, Shi Jin +1
Interference management in multi-stream multi-input multi-output (MIMO) device-to-device (D2D) networks often leads to weighted sum-rate maximization with sum-log-determinant invol…
