Abstract:
A noise cancellation system comprises a first noise cancellation apparatus configured to process an I-channel signal, wherein an I-channel differential mode second-order intermodulation component and an I-channel common mode second-order intermodulation component cancel each other in the first noise cancellation apparatus and a second noise cancellation apparatus configured to process a Q-channel signal, wherein a Q-channel differential mode second-order intermodulation component and a Q-channel common mode second-order intermodulation component cancel each other in the second noise cancellation apparatus.
