An Achievable Rate Region for the 3-User-Pair Deterministic Interference Channel
Achievable Rate Region 3-User-Pair Deterministic Interference Channel
2015/8/17
This paper presents a new coding scheme and a corresponding achievable rate region for a class of deterministic interference channels with three sender–receiver pairs (3-DIC).The codebook structure us...
A lower bound on the secrecy capacity of the wiretap channel with state information available causally at both the encoder and decoder is established. The lower bound is shown to be strictly larger th...

Multiple-Access Channels with Distributed Channel State Information
Multiple-Access Channels Distributed Channel State Information
2015/8/17
This paper considers a multiple-access channel with two state components, where the first sender knows only the first state component, the second sender knows only the second component, and the receiv...
Energy-efficient Packet Transmission over a Multiaccess Channel
Energy-efficient Packet Transmission Multiaccess Channel
2015/8/17
We investigate the minimum-energy packet scheduling problem for the multiaccess channel with K transmitters and a single receiver, assuming that packets arrive at each transmitter’s buffer at arbitrar...
A relay channel consists of an input x,, a relay output yl, a cJmnnel output y, and a relay sender x2 (whose trasmission is allowed to depend on the past symbols y,). l%e dependence of the received sy...

Marton’ s Coding Theorem Discrete Memoryless Broadcast Channel
2015/8/12
A simple proof using random partitions and typicality is given for Marton’ s coding theorem for broadcast channels.
The Capacity of the Physically Degraded Gaussian Broadcast Channel with Feedback
Physically Degraded Gaussian Broadcast Channel Feedback
2015/8/12
Bounds on the output entropy of the additive white Gaussian noise (AWGN) channel with feedback are used to prove that the capacity of the degraded additive white Gaussian noise (DAWGN) broadcast chann...
An Outer Bound to the Capacity Region of the Broadcast Channel
Outer Bound Capacity Region Broadcast Channel
2015/8/12
An outer bound to the capacity region of the two-receiver discrete memoryless broadcast channel is given. The outer bound is tight for all cases where the capacity region is known. When specialized to...
Iterative Channel-Tracking Techniques for 5.9 GHz DSRC Applications
Iterative Channel-Tracking Techniques 5.9 GHz DSRC
2009/9/4
This letter proposes a novel channel-tracking scheme to improve the performance of the dedicated short-range communication (DSRC) systems affected by rapid fluctuations in channel envelopes. The propo...
Training Sequence Length Optimization for a Turbo-Detector Using Decision-Directed Channel Estimation
Training Sequence Length Optimization Turbo-Detector Decision-Directed Channel Estimation
2009/9/4
We consider the problem of optimization of the training sequence length when a turbo-detector composed of a maximum a posteriori (MAP) equalizer and a MAP decoder is used. At each iteration of the rec...
Time Domain Method for Precise Estimation of Sinusoidal Model Parameters of Co-Channel Speech
Time Domain Method Sinusoidal Model Parameters Co-Channel Speech
2009/9/4
A time domain method to precisely estimate the sinusoidal model parameters of cochannel speech is presented. The method does not require the calculation of the Fourier transform nor the multiplication...

Additive white Gaussian noise digital communication system multiplicative neuron
2010/2/2
During signal transmission, the combined effect of the
transmitter filter, the transmission medium, and additive white
Gaussian noise (AWGN) are included in the channel which distort

Turbo Codes: The Issue of Average Union Upper Bound under Imperfect Channel State Information in Rayleigh Fading Channels
Turbo code imperfect estimate channel state information
2009/7/28
The potential of turbo codes to demonstrate excellent performance in the region of low signal to noise ratio is now a familiar fact. The idea of turbo codes was first introduced by Berrou and was base...
