Optimized finger assignment for improved multicarrier throughput

A wireless communications apparatus, comprising:

• at least one processor configured to:
• determine signal-to-noise ratios (SNR) and/or packet error rates (PER) for a plurality of carriers over which signals are received and demodulated;
• dynamically allocate resources to a plurality of demodulators affecting the SNRs and/or PERs to determine an allocation for demodulating the signals at an increased total throughput;
• demodulate the signals over the demodulators utilizing a determined allocation;
• and
• reallocate one or more demodulation fingers from a first demodulator to a second demodulator based at least in part on a projected change in overall throughput, wherein the projected change in overall throughput is projected based at least on a non-linear response of a data rate of a frequency carrier to a potential change in a signal-to-noise ratio (SNR) of the frequency carrier related to the first demodulator;
• and
• a memory coupled to the at least one processor.

A wireless communications apparatus that facilitates dynamic allocation of multicarrier receiver demodulation resources, comprising:

• means for receiving quality measurements of a plurality of carriers over which signals are received;
• means for allocating demodulation resources to a plurality of demodulators, each of which relate to one of the plurality of carriers, based at least in part on the quality measurements of the plurality of carriers to improve overall throughput;
• and
• means for reallocating one or more demodulation fingers from a first demodulator to a second demodulator based at least in part on a projected change in overall throughput, wherein the projected change in overall throughput is projected based at least on a non-linear response of a data rate of a frequency carrier to a potential change in a signal-to-noise ratio (SNR) of the frequency carrier related to the first demodulator.

A computer program product, comprising:
