A Note On The Free Distance Of A Convolutional Code, Alexander Miczo Oct 1969

A Note On The Free Distance Of A Convolutional Code, Alexander Miczo

Electrical Engineering and Computer Science - Technical Reports

A counterexample to a conjecture on the number of constraint lengths required to achieve the free distance of a rate l/n systematic convolutional code is presented.


Generalized Threshold Decoding Of Convolutional Codes, Luther D. Rudolph Jul 1969

Generalized Threshold Decoding Of Convolutional Codes, Luther D. Rudolph

Electrical Engineering and Computer Science - Technical Reports

It is shown that any rate l/b systematic convolutional code over GF(p) can be decoded up to its minimum distance with respect to the decoding constraint length by a one-step threshold decoder. It is further shown that this decoding method can be generalized in a natural way to allow “decoding” of a received sequence in its unquantized analog form.
