Receive path

A receiver comprising:

• a processing module configured to:
• receive a first portion of a packet of a received signal from a first antenna;
• receive a carrier estimate signal;
• adjust a frequency and/or a phase of the first portion based on the carrier estimate signal to provide a first corrected signal;
• and
• correlate the first corrected signal with an expected code sequence to provide a first correlated signal;
• a tracking module configured to:
• receive the first correlated signal;
• and
• update the carrier estimate signal based on the first correlated signal,
• wherein the processing module is further configured to:
• receive a second portion of the packet from a second antenna;
• receive the carrier estimate signal based on the first correlated signal;
• adjust a frequency and/or a phase of the second portion based on the carrier estimate signal to provide a second corrected signal;
• and
• correlate the second corrected signal with the expected code sequence to provide a second correlated signal, and
• wherein a receive path further comprises a phase calculation module configured to:
• receive the first correlated signal and determine a first carrier phase based on the first correlated signal;
• receive the second correlated signal and determine a second carrier phase based on the second correlated signal;
• and
• determine an angle of arrival of the packet of the received signal based on the first carrier phase and the second carrier phase;
• wherein the receiver is further configured to:
• enable the tracking module during receipt of the first portion such that the tracking module is configured to update the carrier estimation signal;
• and
• disable the tracking module prior to receipt of the second portion such that the carrier estimate signal remains constant during receipt of the second portion.
