Abstract :
A maximum likelihood based, iterative, blind data and channel estimation algorithm is presented. The receiver is assumed to have NA>1 element antenna array. The algorithm that is developed for SIMO communication channels involves least-squares estimation for the channel, and maximum likelihood sequence estimation for the information sequence estimation
