    The orthogonal frequency division multiplexing (OFDM) is used to transport data at a rapid rate. Due to the dynamic nature of the network, the bit error rate is the main problem with OFDM. The extra codes used in space-time trellis coding help to lower bit rate error on multipath fading channels. This study uses space-time trellis coding on a wireless channel to improve the bit error rates. In this work, space-time trellis codes with KALMAN filters are used to improve  the bit error rate over wireless channels. The proposed modal  is simulated in MATLAB software, and the results exhibit that the figure of bit error rate has decreased in network
