Abstract
A method for processing signals received in a communications system determines symbol information corresponding to a re-transmitted packet, compared the symbol information of the re-transmitted packet with symbol information of an original packet, and formed a combined packet based on a result of the comparing step.
Claims52
A method for processing signals received in a communications system, comprising:
- determining symbol information corresponding to a re-transmitted packet;
- comparing the symbol information of the re-transmitted packet with symbol information of an original packet;
- and
- forming a combined packet based on a result of the comparing step.
1 more element
A communications receiver, comprising:
- a processor which determines symbol information corresponding to a packet;
- a comparator which compares the symbol information of the re-transmitted packet with symbol information of an original packet;
- and
- a combiner which forms a combined packet based on a result of the comparing step.
1 more element
A diversity combining method, comprising:
- (a) demodulating a re-transmitted packet which includes a plurality signals;
- (b) deriving a symbol for each signal in the demodulated re-transmitted packet;
- (c) detecting error in the re-transmitted packet;
- (d) combining the symbol for each signal in the re-transmitted packet with a symbol for a corresponding signal in an original packet;
- (e) determining a symbol values based on a result of the combining step;
- and
- (f) performing error detection based on the symbols value, and from the secondly decoded;
- and
- (g) requesting packet re-transmission if an error is detected in step (f).
