OPTIMIZED FINGER ASSIGNMENT FOR IMPROVED MULTICARRIER THROUGHPUT

摘要

Systems and methodologies are described that facilitate dynamically allocating demodulation resources of a wideband receiver to provide improved demodulation of simultaneously received signals. Signal-to-noise ratio (SNR) and/or packet error rate (PER) can be measured for the plurality of carriers to determine which demodulators related to the carriers require more resources than others to demodulate signals at a specified signal quality. Where the SNR of a related carrier is high and/or PER is low, the demodulator can require fewer resources than where the SNR of a related carrier is low and/or PER is high. In this regard, the resources are dynamically allocated among the demodulators and reallocated where SNR/PER changes and/or additional resources are made available.

1. A method for dynamically allocating demodulation resources for a wideband wireless communication receiver, comprising:
receiving a plurality of quality measurements related to a plurality of frequency carriers over which signals are received; comparing the quality measurements to determine an allocation of resources to a plurality of demodulators for demodulating the signals at an increased total throughput; allocating the resources to the demodulators according to a determined allocation; and reallocating one or more resources from a first demodulator to a second demodulator based at least in part on a change in quality measurement of a frequency carrier related to at least one of the first demodulator and the second demodulator.
