It has been established that the criteria for space-time convolutional code (STCC) are based on the maximization of the minimum rank and the minimum determinant of distance matrix over quasistatic flat Rayleigh fading channel. This letter presents a new criterion, i.e., modified trace criterion which maximizes both the minimum trace and the average trace of distance matrix for a new STCC. A new STCC is systematically searched so as to maximize the minimum trace and the average trace, and shown to be superior to other known codes in quasistatic flat Rayleigh fading channel.
