Abstract

This paper presents a MIMO (Multiple Input Multiple Output) system adopting tapped delay line (TDL) structure in the receiver for the broadband communication using STBC (Space-Time Block Coding) scheme under FSF. The system fully utilizes the received signal and its complex conjugated version, and two weights corresponding to each symbol in data block of STBC work in pair to extract their own target. Those weights are determined based on the maximum SINR (Signal to noise plus interference) criterion. The proposed method have an ability to take in the desired signal contained in delayed wave without help of data extension, and this advantage is verified through computer simulations.
