    摘要： A user equipment includes an estimator. The estimator is configured to select a first estimate of a signal-to-noise (SNR) ratio, calculate a first amplitude and first noise variance, calculate a second amplitude and a second noise variance, calculate a second SNR, calculate a resolution value, adjust the first SNR, and perform estimation iterations until the resolution value is equal to a predetermined value.

    摘要： A block linear equalizer (BLE) using an approximate Cholesky decomposition is disclosed. The BLE includes channel estimators, a channel monitor unit, a noise power estimator, a parameter selection unit and an approximate Cholesky processor. The channel estimator generates a channel estimate vector from received samples. The channel monitor unit generates a first channel monitor signal for a truncated channel estimate vector and a second channel monitor signal. The noise power estimator estimates a noise power of the received samples. The parameter selection unit selects parameters for approximate Cholesky decomposition based on the first and second channel monitor signals. The approximate Cholesky processor performs block linear equalization on the received samples based on approximate Cholesky decomposition.

    摘要： A Wireless bridge conjoins two previously incompatible technologies within a single device to leverage the strengths of each. The Wireless bridge marries the Personal Area Network (PAN) technology of Bluetooth as described in Bluetooth Specification Version 1.0B with the Wireless Local Area Network (WLAN) technology described in the IEEE802.11a specification to provide a wireless system level solution for peripheral devices to provide Internet service interactions. The invention brings together in a single working device implementations of these technologies so they do not interfere or disrupt the operation of each other and instead provide a seamless transition of a Bluetooth connection to Wireless Local Area Network/Internet connection. From the Wireless Local Area Network perspective the inventive wireless bridge extension allows a Bluetooth-enabled device to roam from one Wireless Access Point (bridge) to the next without losing its back end connection. The invention takes into account the minimum separation and shielding required of these potentially conflicting technologies to inter-operate.

    摘要： A method and block detection receiver for detecting codes carried in a received signal processed into blocks of values. The method includes the steps of arranging the blocks into non-overlapping sets of at least two blocks per set; and for each set, executing a code detection operation over combinations of values, each combination containing one value from each block in the set. A single- or dual-maxima metric generator may be used. Preferably, the number of combinations of values is restricted and the values in a combination are weighted. The block detection receiver executes a form of sequence estimator. Accordingly, performance of the receiver is close to that of coherent detection and is much better than that of the conventional receivers which do not consider more than one consecutive block.
