DOWNLOAD EBOOKFading and Interference Mitigation in Wireless Communications will help readers stay up to date with recent developments in the performance analysis of space diversity reception over fading channels in the presence of cochannel interference. It presents a unified method for computing the performance of digital communication systems characterized by a variety of modulation and detection types and channel models. The book includes coverage of multichannel reception in various fading environments, influence of cochannel interference, and macrodiversity reception when channels are simultaneously affected by various types of fading and shadowing.

DOWNLOAD EBOOKWe consider interference suppression in several wireless communication systems. The first topic treated is self-interference encountered among cooperating systems, for example, the self-interference that is encountered in cognitive radio systems and ultra-wideband (UWB) communication systems. Both single-carrier, direct sequence signals and multicarrier signals are considered, and the effects of the interference on the performance of a direct sequence UWB system that employs channel state estimation in the presence of the interference is evaluated. The second topic that is treated is the mitigation of narrowband interference in block-modulated multicarrier systems. Two schemes, multicarrier code-division multiple access (MC-CDMA) and orthogonal frequency division multiplexing (OFDM), are investigated. The inherent frequency diversity of MC-CDMA through the use of spreading codes allows for robustness against interference. Conversely, OFDM must employ a signal processing technique to suppress the interference due to its lack of frequency diversity. The performance of OFDM is improved with the addition of forward error correction (FEC) coding in the frequency domain, thereby providing the system with frequency diversity. The third topic is the suppression of interference in multiple input, multiple output (MIMO) wireless communication systems that employ multiple-transmit and multiple-receive antennas to increase the data rate and achieve signal diversity in fading multipath channels. Interference in MIMO wireless communication systems usually consists of intersymbol interference (ISI) due to channel multipath dispersion and cross-talk, or interchannel interference, due to the simultaneous transmissions from the multiple-transmit antennas. The focus of the section is on point-to-multipoint (broadcast) MIMO systems in which the channel characteristics are assumed to be known at the transmitter, so that interference mitigation can be performed at the transmitter.

DOWNLOAD EBOOKThis volumes discusses various aspects regarding the capacity/achievable data rate of stationary Rayleigh fading channels. First, it analyses bounds on the achievable data rate with zero-mean proper Gaussian input symbols, which are capacity achieving in the coherent case, i.e., in case of perfect channel knowledge at the receiver. These bounds are tight in the sense that the difference between the upper and the lower bound is bounded for all SNRs. The lower bound converges to the coherent capacity for asymptotically small channel dynamics. Furthermore, these bounds are extended to the case of multiple-input multiple-output (MIMO) channels and to the case of frequency selective channels. In a further part, the present work studies the achievable rate with receivers based on synchronized detection and a code-aided channel estimation. For a specific type of such a receiver an approximate upper bound on the achievable rate is derived. The comparison of this approximate upper bound and the achievable data rate with receivers using synchronized detection based on a solely pilot based channel estimation gives an approximate upper bound on the possible gain by using this kind of code-aided channel estimation in comparison to the conventional receiver using a solely pilot based channel estimation. In addition, the achievable data rate with an optimal joint processing of pilot and data symbols is studied and a lower bound on the achievable rate for this case is derived. In this context, it is also shown which part of the mutual information of the transmitter and the receiver is discarded when using the conventional receiver with synchronized detection based on a solely pilot based channel estimation.
