摘要：
Using oversampling and the finite-alphabet property of digital communication signals, it is possible to blindly identify an FIR channel carrying a superposition of such signals, provided they have the same (known) period, and certain rank conditions on the data and channel matrices are satisfied, In particular, this technique allows separation of finite alphabet signals, removal of intersymbol interference, and synchronization of the signals, An algorithm is proposed and tested on simulated data.
