Abstract:
A method of operating a spread spectrum communications receiver, comprising the steps of:demodulating a current path group with a demodulator; wherein the current path group comprises one or more current paths; and wherein the demodulating step comprises demodulating the one or more current paths with a respective one more demodulation elements; determining one or more survey groups at the receiver, wherein each survey group comprises a unique combination of one or more new paths and zero or more current paths; determining a quality measure of the current path group; determining a quality measure of the one or more survey groups; selectively assigning a selected one of the one or more survey groups to respective elements of the demodulator in place of the current path group in response to a comparison of the quality measure of the selected one of the survey groups with the quality measure of the current path group; and wherein the quality measure is responsive to a power of each path in a group and multiple forms of diversity within a group.
