On the performance of the quadratic receiver for Rayleigh fading channels
Proceedings of ICUPC '95 - 4th IEEE International Conference on Universal Personal Communications, 2002We investigate maximum likelihood sequence estimation (MLSE) of data sequences transmitted over time-varying frequency-selective Rayleigh fading channels. We present the optimal receiver designed to exploit perfect channel state information (CSI) at the beginning of the data sequence and the optimal receiver which does not use this information. For any

Minimum duration outages in Rayleigh fading channels
IEEE Transactions on Communications, 2001Minimum duration outages have been introduced for lognormal shadow fading where the durations of signal fades were considered in evaluating outages. We develop and analyze such minimum duration outages for channels susceptible to Rayleigh fading. The results show that under typical Doppler frequencies the outages due to Rayleigh fading are more likely ...

Channel parameter estimation in Rayleigh fading channel
Electronics and Communications in Japan (Part III: Fundamental Electronic Science), 2005In wireless communication environments such as indoors and in a relatively narrow region for which applications have recently started, the information transmission speed is sufficiently faster than the fading variation. In such cases, the fading variation can be viewed as a colored probability process with autocorrelation.

Conditions for Cooperative Transmission on Rayleigh Fading Channels
2014 IEEE 80th Vehicular Technology Conference (VTC2014-Fall), 2014We consider a system of two nodes transmitting to an access point on quasi-static Rayleigh fading channels. We use signal-to-noise ratio (SNR) thresholds to characterize the requirements of each node, in terms of throughput and reliability, and we study their impact on outage probability.

A case for considering hyper-Rayleigh fading channels
IEEE Transactions on Wireless Communications, 2007This work is motivated by the problem of characterizing small-scale radio propagation environments for wireless sensor networks. If sensors are statically deployed near the ground or within structures, temporal fading may not exist but the channel may nevertheless experience severe frequency-selective behavior.

Variable-Rate Transmission for Rayleigh Fading Channels
IEEE Transactions on Communications, 1972A modulation system is proposed that continuously adjusts its data rate in response to signal strength variations in a fading channel. The optimum variation of data rate with channel conditions is determined, and includes the effects of feedback channel time delay, the interval between rate changes, and restriction of the number of allowable rates ...
