A radio receiver device is arranged to receive a radio signal including a data packet having an address portion and a payload portion, said radio receiver comprising: a first demodulation circuit portion arranged to demodulate the data packet and produce a first estimate of the address portion and a first estimate of the payload portion; a second demodulation circuit portion arranged to demodulate the data packet and produce a second estimate of the payload portion; a first comparison circuit portion arranged to compare said first and second estimates of the payload portion and produce a flag only if they are identical; and a second comparison circuit portion arranged, upon receipt of said flag, to compare said first estimate of the address portion to an expected address portion and to discard the data packet if they are not identical.
A radio receiver device arranged to receive a radio signal including a data packet having an address portion and a payload portion, said radio receiver comprising:
(canceled)
A radio receiver device arranged to receive a radio signal including a data packet, said radio receiver device comprising a first demodulation circuit portion and a second demodulation circuit portion, said radio receiver device being arranged to compare a first output of the first demodulation circuit portion to a second output of the second demodulation circuit portion and to use said comparison to determine to what extent to use said first and second outputs.
The radio receiver device as claimed in claim arranged to save both first and second outputs to memory and to verify a checksum or cyclic redundancy check associated with each of said outputs in order to determine which, if any, demodulation circuit portion to use.
A method of operating a radio receiver device, said method comprising:
16-26. (canceled)
A method of operating a radio receiver device comprising a first demodulation circuit portion and a second demodulation circuit portion, said method comprising:
28-29. (canceled)
A radio communication system comprising a radio transmitter and a radio receiver device, wherein said radio receiver device comprises first and second demodulation circuit portions and first and second comparison circuit portions, said radio communication system being arranged such that:
A non-transitory, computer-readable medium comprising instructions that, when executed on a suitable processor, cause the processor to operate a radio receiver device such that the radio receiver device:
