    摘要: System and method for improving the detection performance of a wirelessly transmitted signal. A preferred embodiment comprises specifying a desired response for missed channel detection and false alarm probabilities for a plurality of signal qualities and determining if a channel detection threshold is based on missed channel detection or false alarm probabilities for the plurality of signal qualities. A signal quality estimate of a channel can be inferred from a signal quality measurement of a second channel, wherein the channel and the second channel are sourced by a single transmitter. The channel detection threshold can be adjusted based upon the previously determined required response and the signal quality estimate of the channel.

    摘要: System and method for providing additional channels to an existing communications system. A preferred embodiment comprises a coprocessor (such as coprocessor 215) coupled to a modem (such as modem 205), wherein transmissions from the modem are routed to the coprocessor. The coprocessor then can insert transmissions that use the additional channels into the transmission from the modem. Timing consistency can be ensured by the coprocessor using scrambling and channelization codes that are provided by the modem. The use of the coprocessor can allow the use of an existing design for the modem rather than creating a new design when a revision to a technical standard is released, saving time and money for equipment manufacturers.

    摘要: A method is provided to decode data encoded by any block code in a manner that substantially improves the error correction capability of the block codes, and that is independent of the encoder. The structure associated with the method desirably allows the testing of those hypotheses that are known to exist, such that one can use the a priori knowledge of the possible set of hypotheses to only search from among them. The method of decoding data is both advantageous and desirable since knowing the subset of the code word space that is being utilized in essence allows the distance between the code words to be increased yielding significant decoding benefits.
