Distortion Parameters in Software Defined Radios

This course covers the comprehensive understanding of distortion parameters in radios. It starts with an exploration of different parameters such as LO leakage, DC offset, and IQ imbalance, and their effects on various transmitter and receiver topologies. For instance, the course explains how inherent noise in semiconductor devices, flicker noise, and converter noise can impact different signal profiles. It then delves into the distortion parameters of ADC, discussing the effect of phase jitter at the output and how to calculate it. The course also explains the Signal-to-Noise Ratio (SNR) due to jitter and quantization noise. Further, it covers the non-linear distortion, explaining the concept of noise figure in an ADC and its effect on the system's SNR. Lastly, the course discusses the distortion parameters and their impact on signal quality, introducing concepts like Intermodulation Distortion, Intercept Point, 1 dB gain compression point, Carrier to Intermodulation ratio, and Spurious Free Dynamic Range.
