Coded Many-User Multiple Access via Approximate Message Passing
Xiaoqi Liu, Kuan Hsieh, Ramji Venkataramanan
We consider communication over the Gaussian multiple-access channel in the regime where the number of users grows linearly with the codelength. In this regime, schemes based on spa…

Bayes-Optimal Estimation in Generalized Linear Models via Spatial Coupling
Pablo Pascual Cobo, Kuan Hsieh, Ramji Venkataramanan
We consider the problem of signal estimation in a generalized linear model (GLM). GLMs include many canonical problems in statistical estimation, such as linear regression, phase r…
