In this paper we implement space time trellis code using relay fading scenario. We present here the design of the 4psk with 2 transmit antennas and 1,23,4 receiver antennas at 4,8,16& 32 state. In this paper we constructed 4-psk sttc code using rank, determinant and Euclidean distance criterion over Rayleigh fading scenario.
