Abstract :
A calibration technique based on a low-power spread-spectrum tone to assist demodulation is presented. The technique does not impose any requirements on signal modulation, spectral shaping, nor on channel spacing, and is highly spectrum efficient. The performance is analysed in the presence of cochannel and adjacent channel interference, diffused multipath fading and additive white Gaussian noise, and results are presented for M-PSK (M=2,4,8).
