    Abstract: A system and method is provided wherein channel state information assisted MIMO transmission based on singular value decomposition (SVD) (204) (304) simplifies the decoding process. The present invention is a joint source and channel coding system and method for robust wireless multimedia communication. Using the fact that SVD redistributes the channel energy in a descending way, the base layer of the Fine -Grained-Scalability (FGS) (208) is mapped to the highest signal-to-noise (SNR) path to obtain better protection, while other enhancement layers are mapped to other paths such that less important layers are mapped to lower SNR paths in the SVD -decomposed channel. A multiple description code (MDC) (207) is also used in this manner such that at least one coded stream is pr ovided more protection because of the high SNR. This invention pertains to any MIMO based wireless multimedia communication system.

    Abstract: The invention refers to a mobile radio communication system (1) for downlink transmission and to a method for transmitting a signal (s) across at least two downlink paths (5, 6) of a multiple antenna (3, 4) mobile radio communication system (1). The system (1) comprises: - a base station (2) comprising a plurality of antennas (3, 4); - at least one mobile user equipment (8); - at least two downlink paths (5, 6) across at least two of the antennas (3, 4) for transmitting a signal (s) from the base station (2) to the at least one user equipment (8), each downlink path (5, 6) comprising a complex channel coefficient (h , h ); and - a feedback path (9) for returning information on at least one complex weight (w) from the user equipment (8) to the base station (2), the at least one complex weight (w) being used for multiplying the signal (s) which is transmitted across at least two of the downlink paths (6). In order to enhance the tolerance of the system (1) against transmission errors (11) on the feedback path (9) it is suggested that the antennas (3, 4) of the base station (2) are disposed in such a distance (a) to one another that the channels of the antennas (3, 4) are correlated. It is further suggested that error detection mechanisms for detecting transmission errors (11) are incorporated in the feedback path (9). Further, it is suggested that error correction mechanisms for correcting transmission errors (11) are incorporated in the feedback path (9). Finally, it is suggested that filter mechanisms (19, 20) are incorporated in the user equipment (8) and in the base station (2).

    Abstract: The disclosed invention implements SVD-MIMO communication efficiently with a less number of high-load calculation required for singular value decomposition (SVD) processing for a channel matrix. A receiver derives a channel matrix H from a reference signal from a transmitter and acquires downlink transmit weights V and receive weights U H by SVD of the channel matrix H. The receiver transmits a reference signal weighted with U* to the transmitter, where U* is a conjugate matrix for U as uplink transmit weights. The transmitter receives the reference signal weighted with U* and separates the signal into downlink transmit weights V and a diagonal matrix D, based on unitary matrix properties.

    Abstract: A method for transmitting/receiving weight information for creating transmission/reception beams in a mobile communication system using a multiple input multiple output adaptive antenna array scheme. The method includes a receiver receiving a predetermined signal, and differentially providing weights to a first scheme and a second scheme for minimizing an error between the received signal and a predetermined reference signal, thereby obtaining a minimum error value. The receiver generates a despread signal by despreading the received signal, produces a reception weight for creation of a reception beam by the receiver through calculation using the despread signal and the minimum error value, and produces a transmission weight for creation of a transmission beam by a counterpart transmitter through calculation using the reception weight and the minimum error value.
