  • Patent number: 8059610
    Abstract: A method and apparatus for implementing hybrid automatic repeat request (H-ARQ) in a multiple-input multiple-output (MIMO) wireless communication system are disclosed. A transmitter transmits at least two data packets via two or more antennas. If at least one of the data packets is not successfully transmitted, the transmitter retransmits the data packets while rearranging the data packets in an orthogonal spreading manner. Alternatively, the transmitter may retransmit only the unsuccessfully transmitted data packet along with a new data packet which replaces a successfully transmitted data packet. The unsuccessfully transmitted data packet may simply be repeated without changing its format. When only the unsuccessfully transmitted data packet is retransmitted along with the new data packet, the transmissions may be combined to recover the retransmitted data packet and the new data packet simultaneously.

  • Patent number: 7869536
    Abstract: A multiple-input multiple-output (MIMO) receiver includes a MIMO decoder, a pre-scaling unit, a demapper, and a post-scaling unit. The MIMO decoder performs a MIMO decoding on received signals to decouple a plurality of symbols transmitted via a plurality of data streams. Both pre-demapping scaling and post-demapping scaling are performed to improve the performance of the receiver. A pre-scaling coefficient is applied to the symbols by the pre-scaling unit to generate pre-scaled symbols. The pre-scaled symbols are converted to soft bits by the demapper. The post-scaling unit then applies a post-scaling coefficient to the soft bits. The post-scaling coefficient is a signal-to-interference and noise ratio (SINR). Cross interference is taken into account in post-demapping scaling to obtain more accurate soft bits for subsequent decoding. The present invention is applicable to both a multi-carrier system, (such as orthogonal frequency division multiplexing (OFDM)), and a single carrier system.

  • Patent number: 7802171
    Abstract: A wireless communication method and system for performing bit-interleaved coded modulation and iterative decoding. The system includes a transmitter and a receiver. The transmitter encodes incoming bits to generate coded bits, punctures the coded bits in accordance with a predetermined puncturing pattern to generate surviving channel bits and stolen bits and interleaves the surviving bits into interleaved surviving bits. The interleaved surviving bits are mapped to channel symbols and the stolen bits are interleaved to generate interleaved stolen bits. At least one of a plurality of antennas is selected to transmit the channel symbols based on the value of the interleaved stolen bits. The receiver receives the transmitted channel symbols, estimates a posteriori probability for both the channel symbols and the stolen bits, and retrieves information of the stolen bits by determining the selected antenna used to transmit the channel symbols.
