It has a simple verilog code to calculate 32 bit hamming distance and a test bench to simulate.

Design HDL code for a circuit that calculates the Hamming distance of two 8-bit inputs.

实现viterbi译码，通过比较最小汉明距来判别最佳路径，删除不必要的路径，最终找到最佳路径。-Implement viterbi decoding, by comparing the minimum hamming distance to distinguish the best path, delete unnecessary path, finally find the best path.

Hamming codes can detect up to two-bit errors or correct one-bit errors without detection of uncorrected errors. By contrast, the simple parity code cannot correct errors, and can detect only an odd number of bits in error. Hamming codes are perfect
