Multi-antenna transmission, or MIMO, is a major enabling technique for broadband cellular networks. The current implementation, however, is mainly for the point-to-point link, and its potential for Space-Division Multiple Access (SDMA) has not been fully exploited. In this paper, we will analytically evaluate the performance of SDMA in multicell networks based on a spatial random network model, where...
In this paper we jointly consider statistical precoding and statistical bit allocation for transmission over correlated MIMO (multiple-input and multiple-output) channels with a linear and zero forcing receiver. Assuming the statistics of the channel is available to the transmitter, we will derive BER bounds using the statistics of subchannel error variances. The bounds are then used to design statistical...
In this paper, we consider the bit rate maximizing problem and power minimizing problem with integer bit allocation. We will derive the duality between these two problems. We will show that if a transceiver is optimal for the power-minimizing problem, it is also optimal for the rate maxi-mizing problem, and the converse is true. For the power minimization problem with integer bit allocation, the solution...
In this paper, we developed a joint AMC-ARQ design combining adaptive modulation and coding at the physical layer with automatic repeat request protocol at the data link layer in multiple-input multiple-output(MIMO) orthogonal frequency division multiplexing(OFDM) systems which is converted into a series of parallel and independent flat sub-channels based on channel matrix singular value decomposition(SVD)...
