Abstract: A new circuit implementation of convolutional Projection codes is introduced. The structure of the convolutional P1, P2 and P3 codes are studied, and their generating functions obtained. For a small constraint length convolutional code, one can use the state-diagram technique to obtain the generating function. However, a typical convolutional Projection code has a constraint length of 56. Hence, the state-diagram technique cannot be used realistically to obtain the generating function because of the extremely large number of computations involved. A new technique called the state equation technique has been developed to handle such large, constraint length, convolutional Projection codes. Several examples using the new technique are presented. The results of the examples are compared to the results obtained by the state-diagram technique and the simulation.
