Disclosed herein is a bidirectional shift register which is capable of preventing multi-outputs from both end stages. The shift register includes a plurality of stages for outputting scan pulses forward or reversely based on a start pulse and a plurality of clock pulses with a phase difference. A last one of the stages includes a forward scan controller for making a set node active and a reset node inactive based on any one of the clock pulses and a scan pulse from an upstream stage, a reverse scan controller for making the set node active and the reset node inactive based on any one of the clock pulses and the start pulse, and an output unit for outputting any one of a corresponding scan pulse and a deactivation voltage based on a voltage at the set node, a voltage at the reset node and any one of the clock pulses.

Provided are a receiver and a method for detecting a signal in a multiple antenna system. The receiver includes a filter coefficient calculator and a signal detector. After separating a first signal portion and a second signal portion, the filter coefficient calculator calculates an MMSE filter coefficient using a Matrix Inversion Lemma such that an inverse matrix of the first signal portion has a predetermined constant value regardless of a repetition signal detection process. The signal detector detects a relevant transmission signal from an interference-removed reception signal using the MMSE filter coefficient.
