Abstract :
A semi-blind algorithm for tracking the synchronisation parameters (time delays and frequency offsets) of multiple users in MC-CDMA systems targeted for broadband LMDS applications is proposed. Simulation results show that the proposed algorithm assures accurate estimates with modest computational complexity and is robust against the presence of multiple-access interference.
