Performance of a digital transmitter leakage LMS-based cancellation algorithm for multi-standard radio-frequency transceivers

R Gerzaguet, L Ros, F Belveze, JM Brossier - Digital Signal Processing, 2016 - Elsevier
This paper deals with a joint estimation algorithm that is dedicated to digital compensation of
transmitter leakage pollution in frequency division duplexing transceivers. These
transceivers are affected by transmitter to receiver signal leakage. Combined with the
nonlinearity of amplifying components in the receiver path, the baseband signal received
can be severely polluted by a baseband polluting term. This term is based on the square
modulus of the transmitted signal, and it depends on the equivalent transmitter leakage …
