Abstract: The proposed technique is a heuristic approach to transmit beamforming, an improved BER performance is achieved in the absence of channel statistics. The heuristic beamforming approach based on signal processing technique enables the realization of an alternative to ensure a relatively high degree of satellite coverage directionality without increasing the complexity of satellite payload capability. This paper proposes transmit beamforming in the absence of channel statistical measures. Based on this, system parameters such as Capacity and BER are analyzed. The results obtained are in line with the theoretical values .It is observed that a SNR of 10 dB results in a BER of 10-3.8 for 16 QAM which is a significant improvement over the conventional technique which has a BER of 10-0.5 for the same signal to noise ratio value.
