Block Diagonal Gmd for Zero-padded Mimo Frequency Selective Channels with Zero-forcing Dfe
In the class of systems with linear precoder and zeroforcing (ZF) DFE for zero-padded MIMO frequency selective channels, existing optimal transceiver designs present two major drawbacks. First, the optimal system requires a large number of bits to encode the full precoding matrix. Second, the full precoding matrix leads to complex computations. These disadvantages become more severe as bandwidt...

متن کاملZero-forcing DPC beamforming design for multiuser MIMO broadcast channels
The sum rate maximization in multiuser MIMO broadcast channels is investigated in this paper. We first propose an approach under a total power constraint. Compared with the most related methods in the literature, the proposed method can be easily adapted to a more realistic per-antenna power constraint. Since the power of each antenna is limited individually by the linearity of its power amplif...
متن کاملMIMO Transceiver Design for Multi-Antenna Communications over Fading Channels
In wireless communications, the use of multiple antennas for both transmission and reception is associated with performance gains of fundamental nature. One such gain stems from the spatial-multiplexing capabilities of wireless multipleinput multiple-output (MIMO) channels: Many propagation environments admit several data streams to be conveyed in parallel over a single point-to-point link, set...
متن کاملModulus Zero-Forcing Detection for MIMO Channels
We propose a modulus based zero-forcing (MZF) detection for multi-input multi-output (MIMO) channels. Traditionally, a ZF detector nulls out all interferences from other layers when detecting a current layer, which can yield suboptimal detection-performance due to the noise-enhancement issue. In many communication systems, finite alphabets such as M quadrature-amplitude-modulation (QAM) are wid...
