Abstract :
For multiple transmitters, with over-sampling and multiple antennas at the receiver, an algorithm is presented to achieve blind mitigation of both intersymbol interference (ISI) and multiple access interference (MAI) by selectively periodically varying the transmitted power of each user. In addition, the permutation ambiguity of many source separation algorithms is overcome
