Method and system for mitigating the effects of a transmitted blocker and distortions therefrom in a radio receiver

A method for reducing leakage noise occurring in a receive path of a radio system, the method comprising the following steps:

• (a) forwarding a transmit signal from a transmit path of the radio system to a first filter, wherein the transmit signal is either in a baseband frequency range or in a low intermediate frequency range;
• (b) scaling the transmit signal using the first filter;
• and
• (c) forwarding the scaled transmit signal to a canceling down-converting mixer (CDM) in the receive path, wherein the CDM comprises circuitry to:
• (i) subtract a first corrective signal from a radio-frequency (RF) receive path signal;
• (ii) subtract a second corrective signal from the RF receive path signal, wherein the second corrective signal includes an approximation of a blocker being caused by and leaking from the transmit signal, and wherein subtracting the second corrective signal results in canceling at least a portion of the blocker;
• (iii) down-convert a resulting corrected RF receive path signal;
• (iv) filter the down-converted corrected signal in a second filter;
• (v) up-convert the filtered corrected signal to create the first corrective signal;
• and
• (vi) up-convert the scaled transmit signal to create the second corrective signal.
