1. A direct sequence spread spectrum (DSSS) receiver, comprising: an antenna wherein the antenna receives a DSSS signal; signal-to-noise ratio (SNR) estimation logic wherein the SNR estimation logic is coupled to the antenna; preamble detection logic coupled to the SNR estimation logic; and a sampler coupled to the antenna, SNR estimation logic, and preamble detection logic; wherein the preamble detection logic comprises: difference logic; accumulation logic coupled to the difference logic; and correlation logic coupled to the accumulation logic; wherein the correlation logic further comprises a offset quadrature phase shift keying ( 0 -QPSK) demodulator.
