Error Performance Analysis of Modified Viterbi Decoding for Interferences

List Viterbi Decoding with Continuous Error Detection

The List Viterbi Algorithm (LVA) with an arithmetic coding based continuous error detection (CED) scheme is applied to high-order partial-response magnetic recording channels. Commonly used magnetic recording systems employ distance-enhancing codes along with parity-check post-processors to correct most dominant error events. The system presented here inserts a CED encoder between the outer Ree...

Block Error Probability using List Viterbi Decoding with Hard Decisions

We consider the List Viterbi Algorithm (LVA) for block decoding of a concatenated channel coding system. The inner code is either convolutional or rate compatible punctured convo-lutional (RCPC), and the outer code is a cyclic redundancy check (CRC). The block error probability is deened as the probability that the transmitted sequence is not in the list of L candidates considered by the LVA. W...

Truncation length for Viterbi decoding

A bound is derived and analyzed for the bit error rate (BER) of a Viterbi decoder with survivor truncation. Estimates of the SNR loss on the AWGN channel, due to truncation are obtained for convolutional codes. Larger truncation lengths are required than the smallest value that does not effectively decrease the code’s free distance, especially at low Eb/No.

Performance of Viterbi Decoding on Interleaved Rician Fading Channels

In this paper, we investigate the performance of the Viterbi decoding algorithm with/without automatic repeat request (ARQ) over a Rician flat fading channel with unlimited interleaving. We show that the decay rate of the average bit error probability with respect to the bit energy to noise ratio is of order between df and df + 1 at high bit energy to noise ratio for both cases (with ARQ and wi...
