摘要
The present invention is to provide a channel BER estimation method for an adaptive error control scheme to more closely match the channel bit error probability prediction with the actual channel bit error probability, which is transmitted through a radio channel at a transmitting side using a chain code. Viterbi decodes a first sequence, measures an increment of a cumulative pass metric in a period in the Viterbi decoding process, assigns a weight using the measured increase, and uses the allocated weight as information on a channel. Viterbi decoding is performed once again using the error correction and error detection capabilities of the RS code. And encoding the Viterbi-decoded second sequence by performing the repetition, comparing the encoded second sequence with the first sequence, and identifying the number of bits in which the error occurs in the first sequence to determine channel bit error probability. In estimating.
