An enhanced solutioning design for military tactical voice communication systems

Great emphasis has always been placed on military communication especially in the wireless spectrum. There is a need for more robust links with higher probability of intercept at the reception end and lower bit error rate (BER) at the transmission front. This is coupled with the requirement to have minimum exposure to loss or distortion of information. In this paper, we propose an enhanced solutioning design based on receiver and transmitter implementation to develop a wider encompassing solution. The receiver implementation will include the integration of a Speech Enhancement System (SES) where methods for noise estimation and reduction will be briefly introduced. The emphasis is on the employment of Arc-Tangent Square Root (ATSR) nonlinear device in the speech enhancement module for harmonic regeneration. For transmitter implementation, we propose a new modulation scheme - Simultaneous Spatial Modulation (SSM) - that reduces power consumption for the same bit error rate (BER) or given the same power, reduces transmission error, thereby increasing the rate of effective communication. Simulation results are presented to verify the effectiveness of the proposed modulation scheme.
