Abstract:
1. A method of determining operating parameters of a receiver, the method comprising: receiving a radio frequency (RF) input signal over a wireless channel; determining a signal strength of the RF input signal by calculating a power of interfering adjacent channels, interfering alternate channels, and desired channels in the wireless channel; determining interference in the wireless channel; setting a target bit-error-ratio (BER) at which to operate the receiver; based on the signal strength of the RF input signal and the interference in the wireless channel, determining a plurality of combinations of operating parameters for the receiver that meet the target BER; determining, from the plurality of combinations, a combination of operating parameters that minimizes power consumption by the receiver by accessing a table of bit-width and sampling frequency combinations that achieve the target BER for given signal strength and interference conditions; and receiving the RF input signal over the wireless channel according to a wireless communication standard selected from a group consisting of IEEE 802.15.4-2006, IEEE 802.11x-2006, and IEEE 802.16-2006.
