摘要：Recent works on ad hoc network study have shown that achievable throughput can be made toscale linearly with the number of receive antennas even if the transmitter has a single antenna.In this paper, we propose a method pursuing robustness in ad hoc network system when thechannel state information (CSI) of interferers is unavailable. The non-parametric linearminimum mean square error (MMSE) filter is exploited to achieve large fraction of the MMSEfilter transmission capacity employing the perfect covariance matrix information. The keyfeature ingredient to make our approach effective is to exploit the autocorrelation of receivedsignal, which obtains the covariance matrix information without transmission rate loss. Fromthe numerical results, we show that the proposed scheme brings substantial transmissioncapacity gain over conventional MMSE filter using sample covariance matrix.
