      Various PN codes for use in TTC spread-spectrum systems are considered. The evaluation is based on peak magnitudes and amplitude distributions of both the even and the odd autocorrelation and crosscorrelation functions. Furthermore the influence of the phase of a sequence on the correlation parameters is studied, multiple-access characteristics in terms of the total interference parameter are evaluated and synchronous as well as asynchronous code generation is considered.1
