摘要： Apparatus and method for dynamically updating a channel model used for wireless local area network based positioning. In one embodiment, a wireless device includes a positioning system. The positioning system is configured to determine a position of the device based on signals received from wireless local area network access points. The positioning system is also configured to determine a likelihood that the wireless device is positioned at each of a plurality of points of a positioning grid based on a received signal strength value for each of a plurality of access points. The positioning system is further configured to update a reference power estimate for each access point based on the likelihoods. The positioning system is also configured to update the path loss exponent of the channel model.

摘要： Low-complexity synthesis filter bank for MPEG audio decoding uses a factoring of the 64×32 matrixing for the inverse-quantized subband coefficients. Factoring into non-standard 4-point discrete cosine and sine transforms, point-wise multiplications and combinations, and non-standard 8-point discrete cosine and sine transforms limits memory requirements and computational complexity.
