Rateless Coding for Gaussian Channels
— A rateless code—i.e., a rate-compatible family of codes—has the property that codewords of the higher rate codes are prefixes of those of the lower rate ones. A perfect fa...

On the Low-SNR Capacity of Phase-Shift Keying with Hard-Decision Detection
1 The low-SNR capacity of M-ary PSK transmission over both the additive white Gaussian noise (AWGN) and fading channels is analyzed when hard-decision detection is employed at the ...

Low Density Lattice Codes
— Low density lattice codes (LDLC) are novel lattice codes that can be decoded efficiently and approach the capacity of the additive white Gaussian noise (AWGN) channel. In LDLC...

Mutual Information Games in Multi-user Channels with Correlated Jamming
We investigate the behavior of two users and one jammer in an additive white Gaussian noise (AWGN) channel with and without fading when they participate in a noncooperative zero-su...

Robust Joint Source-Channel Coding for Delay-Limited Applications
In this paper, we consider the problem of robust joint source-channel coding over an additive white Gaussian noise channel. We propose a new scheme which achieves the optimal slope...

Capacity of the Discrete-Time AWGN Channel Under Output Quantization
We investigate the limits of communication over the discrete-time Additive White Gaussian Noise (AWGN) channel, when the channel output is quantized using a small number of bits. W...
