Abstract
We propose a new interference nulling operation in V-BLAST (Vertical Bell Laboratories Layered Space Time) to reduce unexpected effects by the channel estimation errors. Assuming that the channel estimation is performed by pseudo-inverse of orthogonal or non-orthogonal training sequence matrix, we derive a better nulling vector which minimizes the power of various terms generated by the channel estimation errors. With simulations, we test the performance of the proposed algorithm.
