| 抄録: | Decoding performance of linear block codes using a trellus is investigated in a Rayleigh fading channel. Two methods for calculate metric values for each bit in a received block are considered: the values are calculated from the received signal envelope sample and demodulator output. Bit error rate (BER) performances between hard decision and trellis decoding are compared using Hamming (7, 4) and Golay (24, 12) codes in computer simulations and laboratory experiments. A simplified trellis decoding algorithm, in which the hard decision output of a bit with an envelope sample greater than the threshold value is accepted as correct, is presented for complexity reduction. Laboratory experimental results for the trellis decoding in combination with Gaussian minimum shift keying (GMSK) modulation and frequency detection are shown. The effect of n-bit A/D-conversion in signal envelope sampling is investigated experimentally. |
