Abstract (in Japanese) (See Japanese page) 
(in English) The transmission performance deteriorate if the combining weights for interference suppression are fixed within a packet during signal separation in linear MIMO reception, since the propagation path changes with time in mobile communica- tions. To solve this problem, the authors apply the null-space expansion technique, which improves transmission performance by forming additional nulls to suppress inter-stream interference using antenna degrees of freedom. In this study, we consider acquiring the past channel information for the null-space expansion technique from multiple locations in the packet. Error rate performance is evaluated using computer simulations when combining weights generated by this technique are applied to the entire packet.
