Space-time convolutional codes over GF(p) for two transmit antennas

We present new space-time trellis codes for two transmit antennas and p-PSK modulations, where p=3. 5. 7.11. 13.17, satisfying the rank and the determinant or the trace criteria. The system utilizes a rate 1/2 convolutional encoder over GF(p), p a prime. Some encoder properties are presented that simplify the code search.
