A modulation code-based blind receiver for memoryless multiuser volterra channels

Abstract

This paper proposes a blind receiver for memoryless multiuser Volterra communication channels based on the use of Modulation Codes (constrained codes) and Second Order Statistics of the received signals. Modulation codes allow to model the transmitted signals as Markov chains that are used to introduce temporal correlation and to ensure the orthogonality of transmitted signal products for several time delays, inducing a Parallel Factor (PARAFAC) decomposition of a tensor composed with spatio-temporal covariance matrices.
