  • Variable rate forward error correction for enabling high performance communication
    Patent number: 7593380
    Abstract: A protocol for optimizing the use of coded transmissions such as over wireless links. In this technique, interframes are first split into segments selected to be an optimum size according to transmission characteristics of the radio channel. Segments are assigned a position identifier and redundancy check sum. Segments are then assembled into blocks and a forward error correction algorithm is applied to the block to generate redundancy bits. The FEC block is then split up among available communication channels and forwarded to the receiver. The inverse process is applied at the receiver. Using this scheme, only segments containing erroneous data need to be resent. A large block size required for high performance forward error correction may therefore be used while at the same time minimizing latencies associated with the need to resend entire blocks when errors cannot be recovered.

  • Method and apparatus for computing SIR of time varying signals
    Patent number: 7590192
    Abstract: A method and apparatus for correcting symbols of a common pilot channel (CPICH) to generate an accurate signal-to-interference ratio (SIR) estimate in a wireless communication system are disclosed. In one embodiment, a non-stationary mean of a group of the CPICH symbols is estimated, the CPICH symbols are delayed, and the CPICH symbols are corrected by dividing the delayed CPICH symbols by the estimated non-stationary mean of the group of CPICH symbols. In another embodiment, a signal power estimate is generated based on the magnitude of CPICH symbols, a noise power estimate is generated by subtracting the signal power estimate from a total power estimate based on the magnitude of the CPICH symbols, and a SIR estimate is generated for symbols that have undergone a time varying gain by dividing the signal power estimate by the noise power estimate.
