Direction of Arrival Estimation under Spread Spectrum Reference Signal Assisted Radio
Show more
Abstract: In the present work, a direction of arrival estimator, under
spread spectrum reference of signal-assisted radio
operating in a Rayleigh fading channel, is proposed. The analysis, which is applied to general receiver antenna array configurations, demonstrates the high
performance of the estimator which is due to the double dispreading (code word
and reference signal). The probability distribution
function of the estimator is extracted and the system’s robustness in regard to
large number of interferers is demonstrated.
