Automatic gain control and baseband preintegration to reduce computation requirements at lower data rates
First Claim
1. A method for processing baseband signals, the method comprising:
- receiving, by a preintegrator, inphase (I) and quadrature (Q) baseband signals; and
selectively reducing an amount of samples of the baseband signals to be processed in a correlator, wherein reducing the amount of samples is based on a data rate of the baseband signals.

Abstract
A method for processing baseband signals according to one embodiment includes receiving I and Q baseband signals; and selectively reducing an amount of samples of the baseband signals to be processed in a correlator, wherein the reduction rate is based on a data rate of the baseband signals. A preintegrator module according to one embodiment includes an automatic gain control section for performing automatic gain control on I and Q baseband signals; a first preintegrator coupled to an output of the automatic gain control section, the first preintegrator being for selectively reducing an amount of samples in the I baseband signal based on a data rate of the I baseband signal; and a second preintegrator coupled to an output of the automatic gain control section, the second preintegrator being for selectively reducing an amount of samples in the Q baseband signal based on a data rate of the Q baseband signal. Additional systems and methods are also presented.
