Method for controlling diversity receivers in a wireless communication device
First Claim
1. A method for controlling diversity receivers in a wireless communication device comprising the steps of:
- determining if the wireless communication device is experiencing poor coverage, wherein the determining comprisesoperating a first receiver and collecting coverage statistics S1,operating the first receiver and a second receiver and collecting coverage statistics S2,determining that the wireless communication device is experiencing poor coverage if coverage statistics S2 is greater than coverage statistics S1, anddetermining that the wireless communication device is not experiencing poor coverage if coverage statistics S2 is not greater than coverage statistics S1;
using the first receiver and the second receiver for diversity, if the wireless communication device is experiencing poor coverage; and
using the second receiver for scanning, if the wireless communication device is not experiencing poor coverage.

Abstract
A method for controlling diversity receivers in a wireless communication device includes the steps of: determining if the wireless communication device is experiencing poor coverage (220), using a first receiver and a second receiver for diversity (230) if the wireless communication device is experiencing poor coverage, and using the second receiver for scanning (240) if the wireless communication device is not experiencing poor coverage. Thus, diversity can be used when needed to improve reception. Both receivers, however, can be used in a non-diversity mode to reduce current drain or to speed up channel acquisition when coverage is not poor.
