20090060012 | SYSTEM FOR TRANSMITTING INFORMATION DATA FROM A TRANSMITTER TO A RECEIVER OVER A NESTED BLOCK CHANNEL - The present invention concerns a system for transmitting information data from a transmitter to a receiver over nested block channel, the transmitter (TRD) comprising an encoder (ENC) following an error correcting code structure, the receiver (RCV) comprising a decoder (DEC) defined according to the error correcting code structure, the nested block channel (NBCH) comprising a scaled BPSK binary modulator (BM), the amplitude of which may vary from one bit transmission to the other. Such system is characterized in that the coding rate (Rc) of the encoder (ENC) or the parameters (D,L) of the nested block channel (NBCH) are selected dependently one from each other to achieve a target diversity order of the system and to maximize the coding gain. | 03-05-2009 |
20090268839 | FULL DIVERSITY HIGH-RATE CODED TRANSMIT BEAMFORMING TECHNIQUES USING PARTIAL-ALGEBRAIC PRECODING, AND ASSOCIATED NEAR-OPTIMAL LOW-COMPLEXITY RECEIVERS - The present invention concerns a system for transmitting data from a transmitter comprising at least two transmitting antennas, an encoder following an error correcting code structure and a transmit beamforming technique to a receiver comprising at least two receiving antennas and a decoder defined according to the error correcting code structure over a transmit beamformed MIMO channel.
