The robust linear transceiver design for the more general model of multicell MIMO downlink system with imperfect channel state information (CSI) is discussed in this paper. Our aim is to minimize the total power of the network while the quality of service (QoS) in terms of mean-square error (MSE) for every user should be strictly guaranteed for every(More)
Minimization of the sum power of secondary users (SUs) equipped with multi-antenna is considered in the context of OFDM cognitive radio (CR) networks with coexisting primary users (PUs). The aggregated interference generated by SUs is constrained under a tolerable level so as to maintain reliable communication for PUs. Meanwhile, the quality of service(More)
This paper studies the jointly distributed transceiver design for time-division-duplex (TDD) multicell downlink systems where there is no exchange information between the Base Stations (BSs). With an aim to minimize the sum MSE under per-BS power constraint, we give a hierarchical iterative algorithm which can be implemented in a distributed manner with low(More)
