Patent ID: 8116414

Claim:
A diversity receiver for receiving a simulcast with a plurality of reception antennas, said diversity receiver comprising: a first reception branch for receiving one broadcast of said simulcast to produce a modulated signal; a second reception branch for receiving the other broadcast of said simulcast to produce a modulated signal; first demodulator means for producing an orthogonal signal from said modulated signal produced in said first reception branch to supply the resulting signal to third demodulator means via adder means; second demodulator means for demodulating said modulated signal produced in said second reception branch to produce a demodulated signal; transmission path decode means for performing error correction decoding on said demodulated signal produced by said second demodulator means; re-modulation means for re-modulating a signal having been subjected to said error correction decoding by said transmission path decode means to produce an orthogonal signal; time adjustment means for asynchronously detecting a demodulated signal having been time-deinterleaved when said transmission path decode means performs said error correction decoding and a demodulated signal having been demodulated by said third demodulator means, employing a time difference between both the demodulated signals as a delay time to delay by said delay time said orthogonal signal produced by said re-modulation means, and thereby producing an interpolated signal; and said adder means for carrier combining said interpolated signal and said orthogonal signal produced by said first demodulator means to thereby produce an interpolated orthogonal signal, which is in turn supplied to said third demodulator means, wherein said third demodulator means performs demodulation in conformity with the carrier modulation scheme for said one broadcast, and wherein said re-modulation means performs re-modulation in conformity with the carrier modulation scheme for said one broadcast.
