...Specifically, it demonstrates the design and implementation of a cancellation system for a SISO system that completely cancels self-interference to the noise floor and consequently achieves the theoretical doubling of throughput....

...For canceling the chain’s own self-talk we use the design from prior work [11]....

...The best known prior algorithm for tuning [11] requires around a millisecond to tune, so we would need 16 ms to tune for a 4 antenna MIMO system which would be untenable even in a slowly changing environment like indoor WiFi (coherence times are on the order of tens of milliseconds), let alone…...

...The above approach doesn’t work because every additional and independent digital cancellation algorithm we use in the receive chain linearly increases the residual interference after cancellation....
