Abstract
Most receiver algorithms based on PARATUCK2model adopted traditional ALS methods in one way and twohops MIMO relay communication system now days. Its lowconvergence speed and high computational cost are main factorsrestricting its application under real-time conditions. For thereason, a novel blind receiver Algorithm based onPARATUCK2 model is proposed based on works of buildingone way and two hops MIMO relay communication system.Firstly, the algorithm adds received data a time dimensionalityon the premise of no supervise sequence, then chooses truncatedwindow reasonable, creates iteration relationship betweenauxiliary matrix and base matrix of right subspace, corrects thechannel parameter adaptively, and make it closer to trueparameters in least error square sense. Computational cost ofthe algorithm is reduced by avoiding Moore Penrosepseudo-inverse operation efficiently through tracking anditerating the singular of matrix. The algorithm also improvesconvergence speed by utilizing the estimated result of previousmoment. Simulation result shows that the algorithm has lowercomputational cost, higher convergence speed than PT2-ALS,and the same estimation performance with ALS premised onthat no supervised sequence added.
