Coding for Constant-Data-Rate Systems-Part II Multiple-Error-Correcting Codes

The study of coding for constant-data-rate systems begun in Part I is continued. A simple pulse model of such a system is introduced which is easier to visualize than the correlation detection scheme of Part I. The Wagner code is extended to two multipleerror-correcting schemes. The efficiency of the Wagner code is evaluated by comparing it with Shannon´s ideal coding. It is shown that the Wagner code is just the minimum probability of error detector for parity-checked sequences of independent binary digits.
