Multiple-input multiple-output (MIMO) communication systems use antenna arrays at both the transmitter and the receiver to offer substantial benefits in terms of rate and reliability. Two standard approaches for communicating in MIMO systems are spatial multiplexing and transmit diversity. Multiplexing sends independent information streams across the transmit antennas to maximize rate while tra...
Reliability of the communication system with spatial multiplexing has been studied. Increasing bandwidth radio channels due to is one most popular and relevant areas modern research in field communications. Solving problem time domain multipath propagation associated a significant increase dimension redundant calculations. Detection makes it difficult take into account frequency dependence ampl...
We use the coherence of a light beam to encode spatial information. We apply this principle to obtain spatial superresolution in a limited aperture system. The method is based on shaping the mutual intensity function of the illumination beam in a set of orthogonal distributions, each one carrying the information for a different frequency bandpass or spatial region of the input object. The coher...
To enable mobile stations (MSs) of secondary users (SUs) in cognitive radio (CR) networks sharing a common channel with MSs of primary users (PUs) is an important but challenging issue. In this paper, a cooperative spatial multiplexing (CSM) scheme is proposed, where base station (BS) in CR network has K antennas and each SU or PU has one antenna only, and BS supports PUs and SUs by K spatial c...
