Convolutional codes: techniques of construction [PDF]
Computational and Applied Mathematics, 2014 In this paper we show how to construct new convolutional codes from old ones by applying the well-known techniques: puncturing, extending, expanding, direct sum, the (u|u + v) construction and the product code construction. By applying these methods, several new families of convolutional codes can be constructed.
