“…The case of unavailable realization of at the receiving site gives rise also to various equalization procedures, which bear their own information-theoretic implications referring to the specific interpretation of the equalization method on one hand [16], [21], [58], [250], and the to information-theoretic role of the accuracy of the available channel parameters [185]- [186] on the other hand. This framework gives also rise to natural questions of how information-theoretically efficient are training sequence methods [140] and the like.…”

“…As expected, capacity of the AWGN channel is approached with the increase of the number of diversity branches. See also [21], [302], [15], [72], [174], and many other references provided in the reference list here and reference lists of the cited papers. With no CSI, it has been demonstrated in [87] that for the Rayleigh fast flat-fading channel, the capacityachieving distribution remains discrete in its input norm for receiver space diversity as well.…”

Abstract-In this paper we review the most peculiar and interesting information-theoretic and communications features of fading channels. We first describe the statistical models of fading channels which are frequently used in the analysis and design of communication systems. Next, we focus on the information theory of fading channels, by emphasizing capacity as the most important performance measure. Both single-user and multiuser transmission are examined. Further, we describe how the structure of fading channels impacts code design, and finally overview equalization of fading multipath channels.

Abstract-Transmit beamforming (BF) with reliable channel state information at the transmitter (CSIT) can improve the system performance significantly. On the other hand, for unreliable CSIT pure space-time coding outperforms transmit BF. In this paper, the combination of time-reversal space-time block codes (TR-STBCs) and transmit BF for transmission over frequency-selective fading channels is considered. The proposed scheme takes the reliability of the CSIT into account in an optimum way. For unreliable CSIT, the proposed scheme yields the same diversity gains as a TR-STBC, whereas for reliable CSIT significant BF gains can be obtained in addition to the diversity gain of the TR-STBC.

“…3, each having a feedforward filter with a temporal span of 1 taps per receive antenna and a feedback filter with a temporal span of taps. Hence, every 1 stage resembles a multiple-input single-output (MISO) DFE, for which a large body of literature exists (see, for instance, [29]- [32] and the references therein). At each stage, the "best" data stream-in the MMSE sense-is extracted, detected, and canceled out.…”

Abstract-Recent results in information theory have demonstrated the enormous potential of wireless communication systems with antenna arrays at both the transmitter and receiver. To exploit this potential, a number of layered space-time architectures have been proposed. These layered space-time systems transmit parallel data streams, simultaneously and on the same frequency, in a multiple-input multiple-output fashion. With rich multipath propagation, these different streams can be separated at the receiver because of their distinct spatial signatures. However, the analysis of these techniques presented thus far had mostly been strictly narrowband. In order to enable high-data-rate applications, it might be necessary to utilize signals whose bandwidth exceeds the coherence bandwidth of the channel, which brings in the issue of frequency selectivity. In this paper, we present a class of layered space-time receivers devised for frequency-selective channels. These new receivers, which offer various performance and complexity tradeoffs, are compared and evaluated in the context of a typical urban channel with excellent results.
