Conventional communication systems use either sinusoids (pass band) or square waves (baseband) as carriers. However tradeoffs have to be made with regards to bandwidth, fidelity, power consumption and system complexity. This paper explores using Non-conventional waveforms including Gaussian like pulses as carrier waveforms using a 4-user OFDMA system as the benchmark. SPICE simulations are done at the deep submicron VLSI level (120 nm) using MicroWind. The performance of the various carrier waveforms are assessed by using standard metrics such as Bit Error Rate, Signal to Noise ratio and eye-diagram. The results presented in this work give valuable insights into Non-conventional carrier waveforms and their impact on SNR and BER leading to more robust.
