ABSTRACT:
A method and apparatus for reducing power consumption within a wireless receiver is provided herein. Particularly, the use of partial chip sequence correlation to reduce the average power consumption of a direct sequence spread spectrum (DSSS) wireless transceiver is provided herein. During operation, the receiver will attempt to correlate, or de-spread, less than all chips that constitute a symbol. A partial correlation may be performed on M chips, where M may be much less than N, the number of chips that represent a whole symbol. In a preferred embodiment, the M chips are the first M chips in the symbol.
