This study uses cutting-edge Field Programmable Analog Arrays (FPAA) technology to demonstrate the implemen- tation of linear modulations such as Double Sideband (DSB), Double Sideband with Suppressed Carrier (DSB-SC), and Single Sideband (SSB). The majority of the problems encountered when utilizing the DCS kit are avoided, thanks to the inclusion of FPAA. Double sideband modulation techniques for developing analog RF transmission systems have been used to create the FPAA circuits. The suggested solution enables reconstructing the analog conditioning step using an FPAA device, which may be tailored to the electrical characteristics and signal shape requirements. The multiplier is used to execute the DSB, DSB-SC Modulation, SSB Modulation, and Demodulation for a sinusoidal carrier signal. The structuresâ\euro™ functional components are created using the customizable analog modules (CAMs) of the FPAAs AN231E04 and AN220E04 from Anadigm designer2. The findings of the simulations and experiments are in good accord with the theoretical forecasts. An intriguing and promising proposal to implement the DSB, DSB-SC technology is disclosed and is based on the customizable analog blocks (CABs) architecture and Anadigm Designer2 software. The AN231E04 board, a creation of Anadigm Inc., is used to actually construct and verify the system.

Orthogonal Time Frequency Space (OTFS) modulation has established itself as a dependable  protocol for high-speed vehicular communication. This pioneering technique operates within a novel two-dimensional (2D) delay-Doppler domain waveform. When juxtaposed with conventional modulation methods like orthogonal frequency division multiplexing (OFDM), OTFS demonstrates superior performance enhancements in scenarios involving rapidly moving wireless channels. This paper begins by initially unveiling the input-output association of the OTFS signal within the delay-time domain. A comprehensive comparison with the established OFDM waveform highlights the potential of OTFS for achieving notably lower bit error rate (BER) under various conditions, which has been obtained by using the Minimum Mean Square Equalizer (MMSE) equalization technique. Finally, we have proposed novel and low complexity Very-large-scale integration (VLSI) architecture for the OTFS transmitter and the receiver by using the LU decomposition technique for the first time in state-of-the-art. We have shown comparison of computational complexity of both direct implementation and LU decomposition techniques, followed by resource utilization, timing analysis, and functionality testing of the proposed architecture.
