Applications of Sparse Signal Recovery in Broadband Communications

In this talk, I will describe two novel applications of sparse signal recovery in broadband wireless and wireline communications.  In the first wireless application, I will show how to estimate and cancel a frequency-hopping 1 MHz Bluetooth signal interfering with a 20 MHz WiFi signal in the unlicensed 2.4 GHz frequency band.In the second wireline application, I will consider a vectored DSL backhaul link using a 25 copper-twisted-pairs cable binder. Crosstalk between the twisted pairs severely limits the achievable data rate.  I will describe a sparsity-constrained signal processing approach to achieve near crosstalk-free performance using a reduced-complexity sparse digital crosstalk canceller/equalizer
