| 抄録: | The codeword error rate (WER) performance of noncoherent FSK with soft decision decoding of block codes using Chase's second algorithm is investigated in a Rayleigh fading channel. The received signal envelope is sampled and used as channel measurement information. The theoretical upper and lower bounds of the WER are derived, assuming independent Rayleigh envelope samples in a received block. When the Golay (23, 12, 7) code is used, soft decision decoding with 6-bit error correction capability (3-bit error and 3-bit erasure) requires an average signal-to-noise power ratio about 5 dB lower than that for minimum distance decoding with 3-bit error correction to obtain a WER=10^<-3>. The effects of bit interleaving on the WER performance when fading envelope variations is slow compared to the bit rate are investigated through computer simulations. When 23 x M_i bit interleaving is used for transmitting M_i Golay codewords, the simulation results show that M_i ≈ 0.2 x (bit rate/fading maximum Doppler frequency) is suffcient to obtain the full advantages of soft decision decoding. the theoretical analysis was supported by labratory experoments. |
