Patent ID: 8054918

Claim:
A method of acquiring a radio frequency burst (FB) signal in a wireless communication device, comprising: receiving at a receiver a signal thus providing a received signal; determining at a baseband section autocorrelation function values of the received signal; determining whether the autocorrelation function values of the received signal exhibit a substantial peak; designating the received signal as a frequency burst (FB) signal when the autocorrelation function values thereof exhibit a substantial peak; filtering the received signal with an FB filter until the received signal is designated as an FB signal, and alternatively, filtering the received signal with a channelization filter if an FB signal has already been designated; and applying a frequency bias to the received signal prior to a FB designation and removing the frequency bias once the FB has been designated, wherein determining the autocorrelation function values of the received signal is performed by determining post-normalized autocorrelation values using a predetermined delay lag combined with a predetermined plurality of symbols.
