A Viterbi decoder uses the Viterbi algorithm for decoding a bitstream that has been encoded using forward error correction based on a convolutional code. The Hamming distance is used as a metric for hard decision Viterbi decoders. The squared Euclidean distance is used as a metric for soft decision decoders. WebAt a high level, to decode a point of this polynomial, the decoding algorithm chooses a set of points on a line that passes through the point of interest . It then queries the codeword for the evaluation of the polynomial on points in and interpolates that polynomial. Then it is simple to evaluate the polynomial at the ...

Web1. This happens, because Python float has 53 bits of precision. You can not encode really long strings. You may want to use decimal instead of floats to get arbitrary precision. import sys import random import string import decimal from decimal import Decimal decimal.getcontext ().prec=100 def encode (encode_str, N): count = dict.fromkeys ... Webthe Viterbi decoder algorithm. Now if we are only going to send the 15 data bits given above, in order for the last bit to affect three pairs of output symbols, we need to output two more pairs of symbols. This is accomplished in our example encoder by clocking the convolutional encoder flip-flops WebJun 28, 2024 · Figure 2: Structure of our code.
