Patent ID: 8908792

Claim:
An apparatus, comprising: a transmitter operable to communicate in a wireless network and adapted to use an efficient Golay correlator, wherein the Golay correlator comprises: a sequence of delays D (n) configured to generate at least one sequence of delays, wherein a delay D(n) is selected from a group consisting of any permutation of delay elements; a sequence of multipliers interconnected with an input and the sequence of delays D(n) to apply weight factors; wherein all delays D(n) transmitted by said transmitter are replaced with 1.5D(n) except a first delay which remains 1; wherein said transmitter generates a signal at chip frequency Fc and a receiver in communication with said transmitter samples said signal at 1.5Fc; wherein a first multiplier associated with transmissions from said transmitter is converted to exp(j2π/3) thereby producing an impulse response very close to correlating with original sequences.
