Aawatif Menouni Hayar, B. Lacaze, Daniel Roviras · 2002
This paper presents results obtained by applying periodic clock changes multiple access (PCCMA) to the uplink of mobile multiuser communication systems. Emitted signals are subjected to periodic clock changes based on linear time variant filters. At the reception side, we transpose the system in the time invariant domain and apply inverse filtering.
