Abstract

Systems for supporting multi-channel dynamically controlled diversity reception in wireless communications include a plurality M of receivers coupled to M antennas and configured handle N communication channels wherein N≦M≦(2*N−1) and N channel state machines configured to dynamically allocate multiple channels of the N channels to the M receivers to support dynamic switched diversity for multi-channel dynamically controlled reception. Each channel state machine is configured to control the operation of each receiver. Arbitration is performed between channel state machines when such channel state machines work concurrently. In some embodiments, a lock state machine inside each channel state machine accelerates the locking time of a receiver based on at least one parameter received from another receiver.

Claims

1. A system for wireless communication, comprising:

a) a plurality M of receivers coupled to M antennas and configured to handle N communication channels, wherein N≧

2 and wherein N≦

M≦

(2N−

1);

b) N channel state machines configured to dynamically allocate multiple channels of the N channels to the M receivers to support dynamic switched diversity for multi-channel dynamically controlled reception;

c) an arbitration component configured to arbitrate between channel state machines when such channel state machines work concurrently; and

d) a fast lock control mechanism operative to accelerate the locking time of one receiver based on at least one parameter received from another receiver.

2. The system of claim 1, wherein the fast lock mechanism includes, for each channel state machine, a lock state machine configured to receive an input parameter and a copy command parameter from another lock state machine.

3. The system of claim 2, wherein the input parameter is selected from the group consisting of an initial receiver gain, a frequency shift and a combination thereof.

4. The system of claim 2, wherein the copy command parameter is selected from the group consisting of a set gain command, a frequency shift command and a combination thereof.

5. The system of claim 1, wherein each channel state machine is configured to control the operation of each receiver.

6. The system of claim 5, wherein each receiver is dynamically configured to process a single channel.

7. The system of claim 5, wherein the arbitration includes allocation of an available receiver per priority of a processed channel.

8. The system of claim 1 wherein the arbitration includes allocation of a different time slot to each channel state machine.

9. A method for wireless communication, comprising steps of:

a) providing a plurality M of receivers coupled to M antennas and configured to handle N≧

2 communication channels, wherein N≦

M≦

(2N−

1); and

b) dynamically allocating the N channels to the M receivers while considering channel priority, thereby supporting dynamic switched diversity for multi-channel dynamically controlled reception, wherein the step of dynamically allocating includes configuring N channel state machines to perform the dynamic allocation of multiple channels to receivers and wherein the configuring N channel state machines to perform the dynamic allocation of multiple channels to receivers includes accelerating a locking time of one receiver based on at least one parameter received from another receiver.

10. The method of claim 9, wherein the accelerating is performed by a lock state machine included in each channel state machine, each lock state machine configured to receive an input parameter and a copy command parameter from another lock state machine.

11. The method of claim 10, wherein the input parameter is selected from the group consisting of an initial receiver gain, a frequency shift and a combination thereof.

12. The method of claim 10, wherein the copy command parameter is selected from the group consisting of a set gain command, a frequency shift command and a combination thereof.

13. The method of claim 9, wherein the step of dynamically allocating the N channels to the M receivers while considering channel priority includes dynamically configuring each receiver to process a single channel.

14. The method of claim 9, further comprising the step of arbitrating between channel state machines when such channel state machines work concurrently.

15. The method of claim 14, wherein the step of arbitrating includes allocating a different time slot to each channel state machine.

16. The method of claim 14, wherein the step of arbitrating includes allocating an available receiver per priority of a processed channel.
