Joint estimation of channel and carrier frequency offset from the emitter, in an uplink OFDMA system
13 years 7 days ago
In this paper, we propose a joint estimation method of carrier frequency offsets (CFO) and channel impulse responses (CIR) for an uplink OFDMA system. We consider the CFOs come in...
