Systems and techniques are disclosed relating to reducing the number of fingers in a rake receiver used for rake finger processing in wireless networks. Determining Ebefore, captured energy of all fingers before increasing transmit power. Increasing transmit power by a delta transmit power. Determining Eafter, captured energy of i fingers. Determining i fingers needed for processing, such that Eafter is essentially greater than or equal to Ebefore.

What is claimed is: 1. A method for controlling rake finger processing in a receiver, the method comprising: determining Ebefore, captured energy of all fingers before an increase in transmit power; determining Eafter, captured energy of i fingers after the increase in transmit power; and determining i fingers needed for processing, such that Eafter is essentially greater than or equal to Ebefore. 2. The method of claim 1, wherein the increase in transmit power is 3 dB. 3. The method of claim 1, wherein the increase in transmit power is based on a desired reduction in receive power consumption. 4. The method of claim 1, wherein the increase in transmit power is based on a signal-to-interference-and-noise ratio (SINR). 5. The method of claim 1, wherein the increase in transmit power is based on a multipath power profile. 6. The method of claim 1, further comprising transmitting a request to perform the increase in transmit power. 7. A wireless terminal, comprising: a transceiver coupled to an antenna; a demodulator including a searcher and a plurality of fingers; a microprocessor coupled to the demodulator; the microprocessor configured to: determine Ebefore, captured energy of all of the plurality of fingers before an increase in transmit power; determine Eafter, captured energy of i fingers after the increase in transmit power; and determine i fingers of the plurality of fingers needed for processing, such that Eafter is essentially greater than or equal to Ebefore. 8. The wireless terminal of claim 7, wherein the increase in transmit power is 3 dB. 9. The wireless terminal of claim 7, wherein the increase in transmit power is based on a desired reduction in receive power consumption. 10. The wireless terminal of claim 7, wherein the increase in transmit power is based on a signal-to-interference-and-noise ratio (SINR). 11. The wireless terminal of claim 7, wherein the increase in transmit power is based on a multipath power profile. 12. The wireless terminal of claim 7, wherein the microprocessor is further configured to transmit a request to perform the increase in transmit power. 13. Computer readable media embodying a program of instructions executable by a computer program, said computer readable media comprising: a computer readable program code means for determining Ebefore, captured energy of all fingers before an increase in transmit power; a computer readable program code means for determining Eafter, captured energy of i fingers after the increase in transmit power; and a computer readable program code means for determining i fingers needed for processing, such that Eafter is essentially greater than or equal to Ebefore. 14. A wireless terminal, comprising: means for determining Ebefore, captured energy of all fingers before an increase in transmit power; means for determining Eafter, captured energy of i fingers after the increase in transmit power; and means for determining i fingers needed for processing, such that Eafter is essentially greater than or equal to Ebefore.
