An Algebraic Approach to Constraint Satisfaction Problems
A constraint satisfaction problem, or CSP, can be reformulated as an integer linear programming problem. The reformulated problem can be solved via polynomial multiplication. If t...

Scalable Design of Space-Time Trellis Code with Low Decoding Complexity
—Design of space-time codes that scale with the number of transmit antennas is a difficult problem. In this paper, we introduce a new family of space-time trellis codes (STTC) th...

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...
