AI Technical Summary
In communication devices with shared transmit and receive paths, leakage of transmission signals into the receive path causes distortion components, such as second-order IMD and spurs, leading to degraded Signal-to-Noise Ratio (SNR) in the baseband receive signal.
A transceiver system that filters and processes the baseband transmit signal using a configurable transfer function based on the leakage component, generates an envelope signal representing the distortion, and combines it with the receive signal to cancel out the distortion, utilizing adaptive algorithms to optimize the transfer function.
The system effectively reduces distortion components in the baseband receive signal, improving the SNR by actively estimating and canceling interference, thereby enhancing signal quality.
