Modulated Sparse Superposition Codes for the Complex AWGN Channel
Kuan Hsieh, Ramji Venkataramanan
This paper studies a generalization of sparse superposition codes (SPARCs) for communication over the complex additive white Gaussian noise (AWGN) channel. In a SPARC, the codebook…

Capacity-achieving Spatially Coupled Sparse Superposition Codes with AMP Decoding
Cynthia Rush, Kuan Hsieh, Ramji Venkataramanan
Sparse superposition codes, also called sparse regression codes (SPARCs), are a class of codes for efficient communication over the AWGN channel at rates approaching the channel ca…
