System Performance of Transform Domain Communication Systems with Transceiver Consistency

In this paper, we provide a detailed analysis of the system performance in transform domain communication systems when transmitter and receiver configurations are synchronized. The discussion focuses on performance characteristics under Additive White Gaussian Noise (AWGN) channels and various interference scenarios including single-tone, multi-tone, narrowband, and sweep-frequency interference. We examine signal transmission and reception effectiveness across different conditions, analyzing key influencing factors through algorithms such as frequency domain transformation using FFT operations, interference detection thresholds, and adaptive filtering techniques. The implementation typically involves converting time-domain signals to frequency domain using Fourier transforms, applying spectral nulling for interference avoidance, and utilizing inverse transforms for signal reconstruction. Through comprehensive discussion incorporating code-level insights on spectral processing and interference mitigation strategies, we provide readers with thorough understanding and in-depth analysis to better comprehend system performance in transform domain communication systems with consistent transceiver parameters.
