Patent ID: 8335281

Claim:
A diversity receiving apparatus comprising: a receiving unit operable to receive a frequency-division multiplexing signal that a carrier group including a data carrier, a pilot carrier and a transmission control carrier has been multiplexed thereon to output a receiving signal; a first demodulating unit operable to demodulate the receiving signal to output a first data carrier; a second demodulating unit operable to demodulate the receiving signal to output a second data carrier; a timing adjusting unit operable to synchronize a processing timing of demodulating a carrier group by said first demodulating unit and a processing timing of demodulating a carrier group by said second demodulating unit; and a combining/selecting unit operable to perform at least one of combining the first data carrier with the second data carrier, and selecting one of the first data carrier and the second data carrier, wherein each of said first demodulating unit and said second demodulating unit comprises: an analog-to-digital converter operable to digitize the receiving signal; a wave detecting unit operable to detect a signal outputted by said analog-to-digital converter; and a time-to-frequency converting unit operable to map a signal outputted by said wave detecting unit from a signal along a time axis to a signal along a frequency axis, wherein either said first demodulating unit or said second demodulating unit comprises: a decoding unit operable to decode a transmission control signal from a signal outputted by said time-to-frequency converting unit; and a detecting unit operable to detect frame synchronization from a signal outputted by said time-to-frequency converting unit.
