This paper is concerned with the phase noise mitigation in millimeter wave (mmW) multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems. We first develop a model for phase noise in the mmW MIMO-OFDM system with hybrid precoding. A pilot-assisted estimation and compensation (PEC) scheme is then proposed by jointly estimating the channel response and effective...
When developing gigabit speed communication systems, a lot of design and implementation challenges emerge. And prototype is important to assess the overall system performance and complexity trade-offs under real-world conditions. In this contribution, prototype design and implementation of a time division-fourth generation (TD-4G) system-time division duplex-gigabit speed (TDD-GBPS) demonstration...
In this paper, we consider the multiuser MIMO downlink channel with multiple antennas at both the base station and the users. We concentrate on the case where the transmitter has imperfect channel state information due to estimation error and feedback delay. A channel modification matrix and a scalar factor based on minimum mean square error criterion are derived to form an equivalent channel matrix...
In this paper, a multipath delay estimation scheme for a MIMO-OFDM system is presented. The scheme is achieved by using the same training symbols for each transmitter antenna after performing transmission delay timing estimation. The training sequences which are simultaneously transmitted are specialized for utilizing the peak autocorrelation property. Probability statistics for multipath delay of...
