Low SNR Capacity of Fading Channels – MIMO and multipath
Discrete-time noncoherent Rayleigh fading multiple-input multiple-output (MIMO) channels are considered, with no channel state information at either the transmitter or the receiver. The fading is assumed to be correlated in time and independent from antenna to antenna. Peak and average transmit power constraints are imposed, either on the sum over antennas, or on each individual antenna. In bot...
متن کاملOn the High SNR Capacity of Stationary Gaussian Fading Channels
We present results on the high signal-to-noise ratio (SNR) asymptotic capacity of peak-power limited single-antenna discrete-time stationary complex-Gaussian fading channels with memory, where the transmitter and receiver, while fully cognizant of the fading law, have no access to its realization. Complementing recent results of Lapidoth & Moser about the case where the fading process is regula...
متن کاملOn Phase Noise Channels at High SNR
Lapidoth and Moser have recently proposed a general technique for obtaining upper bounds on channel capacity via a dual expression in which the maximization over probability distributions on the channel input alphabet is replaced with a minimization over probability distributions on the channel output alphabet. They have also introduced the notion of “capacity achieving input distributions that...
متن کاملAdaptive Multipath Fading Prediction on Rayleigh Channels
In mobile radio, Rayleigh fading poses the main threat to accurate data transmission. To solve this problem, an adaptive prediction algorithm of the Rayleigh fading channel is investigated here. We implement the adaptive method based on an autoregressive model of the past fading measurements in the sense of LMSE and predict the future fading multiplicative gain ahead. To mitigate the influence ...
متن کاملA Secure Chaos-Based Communication Scheme in Multipath Fading Channels Using Particle Filtering
In recent years chaotic secure communication and chaos synchronization have received ever increasing attention. Unfortunately, despite the advantages of chaotic systems, Such as, noise-like correlation, easy hardware implementation, multitude of chaotic modes, flexible control of their dynamics, chaotic self-synchronization phenomena and potential communication confidence due to the very dynami...
