    摘要： Described herein are technologies related to an implementation of a system to measure and compensate non-linearity (e.g., echo cancellation) in a transceiver circuitry of a device. Particularly, the echo cancellation utilizes reduced number of components for power savings, and further increases efficiency of signal or data packet transmissions in the device. An echo signal is determined by sampling a power amplifier output signal. The output signal is split into signals with different delays. Down conversion and digital interpolation of the signal with the shortest delay is performed. An echo cancellation signal is calculated based on the output signal as received as an input signal to a receive chain. The calculated signal is subtracted from a received echo signal to generate an echo free signal.
