Patent ID: 7890068

Claim:
A receiving device, comprising: first demodulating means for demodulating data transmitted by at least one of a plurality of propagation paths in a first channel having transfer functions which are different from one another; second demodulating means for demodulating data transmitted by at least one of a plurality of propagation paths in a second channel having transfer functions which are different from one another; and data processing means for merging the data demodulated by the first demodulating means and the data demodulated by the second demodulating means, wherein the data processing means includes data determining means for determining a respective reception state of demodulated data from the first demodulating means and the second demodulating means by determining whether an error exists therein and by determining a state of use of each propagation path of the first and second channels based upon state of use of each propagation path indicated in a field included in the data demodulated by the first demodulating means and the second demodulating means.
