摘要： 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.

摘要： The present invention relates to a chatting system having secret attendance function and the method for operating the same. The chatting system having secret attendance function comprises: an attendance list control system for checking that a connected attendant is a general attendant, or a public attendant, or a secret attendant and registering the attendant; a video control system for receiving video chatting data from the terminals of the connected general attendants; an audio control system for receiving audio chatting data from the terminals of the connected general attendants; and a text control system for receiving text chatting data from the terminals of the connected general attendants. In accordance with the present invention, the attendants in a chatting room cannot recognize the attendance of the secret attendants. In addition, the public attendance can be recognized, however, the public attendants can do text chatting only.
