Error rate performance of the projection code

The operation of the projection code is introduced, and the error rate performance is determined. A new combinatorial generating function technique is used to compute the weight distribution of a cylindrical projection code, which is then employed to obtain upper and lower bounds of the bit error rate of the code. We then apply a state equation technique to compute the generating function of a convolutional projection code. This new generating function technique is needed since the standard state-diagram technique cannot realistically be used to obtain the generating function of a typical convolutional projection code which can have a constraint length of 56.
