Wireless communication system and method with frequency burst acquisition feature using autocorrelation

A method of acquiring a radio frequency burst (FB) signal in a wireless communication device, comprising:

• receiving a signal thus providing a received signal;
• determining autocorrelation function values of the received signal;
• designating the received signal as an FB signal if autocorrelation function values thereof exhibit a substantial peak;
• and
• 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.

A wireless communication system comprising:

• a receiver that provides a received signal;
• a baseband section, coupled to the receiver, that:
• determines autocorrelation function values of the received signal;
• determines if the autocorrelation function values of the received signal exhibit a substantial peak;
• and
• designates the received signal as a frequency burst (FB) signal if the autocorrelation function values thereof exhibit a substantial peak.

A wireless communication system comprising:

• a receiver that provides a received signal, the receiver further including:
• a frequency burst (FB) filter that filters the received signal when an FB has not yet been detected for the received signal, and
• a channelization filter that filters the received signal after an FB has been detected for the received signal;
• a baseband section, coupled to the receiver, that designates the received signal as an FB signal if autocorrelation function values thereof exhibit a substantial peak.

A method of acquiring a radio frequency burst (FB) signal in a wireless communication device, comprising:

• receiving a radio frequency signal;
• filtering the radio frequency signal with an FB filter if an FB has not yet been detected for the radio frequency signal;
• designating the radio frequency signal as an FB if autocorrelation function values thereof exhibit a substantial peak;
• and
• continuing to filter the radio frequency signal with the FB filter after the FB is detected.
