Ahstrrrrt-The Gilbert-Elliott channel is a varying binary symmetric channel with crossover probabilities determined by a binary-state Markov process. In general, such a channel has a memory that depends on the transition probabilities between the states. First, a method of calculating the capacity of this channel is introduced and applied to several(More)
Abstruct-The capacity C(p,, p p) of the discrete-time quadra-ture additive Gaussian channel (QAGC) with inputs subjected to (normalized) average and peak power constraints, pa and pp respectively, is considered. By generalizing Smith's results for the scalar average and peak-power-constrained Gaussian channel, it is shown that the capacity achieving(More)
The capacity of the M-User Binary Adder Channel, subjected to various restrictions of physical nature, is investigated. The underlying propagation media considered are (i) fiber-optical, with lossless coupling and Poisson statistics (ii) radio, under Rayleigh fading and (iii) radio with constant amplitudes and random phases. Whereas the capacity of the(More)
Consider M − HChoose P − T communications: T users or less, out of M potential users, are chosen at random to simultaneously transmit binary data over a common channel. A method for constructing codes that achieve error-free M − HChoose P − T communication over the noiseless Adder Channel (AC), at a nominal rate of 1/ T bits per channel symbol per active(More)
