Wireless communications apparatus and method using array antenna |
摘要 |
<p>A wireless communication apparatus comprises an array antenna configured to receive a signal at multiple antenna elements; a DoA estimation unit configured to estimate directions of arrival of multiple paths contained in the received signal; an angle spread estimation unit configured to estimate an angle spread of the multiple paths; a first weighting calculation unit configured to estimate a common set of weighting factors for all the paths; a second weighting calculation unit configured to estimate an individual set of weighting factors for each of the multiple paths based on the estimated directions of arrival of the paths; a weighting unit configured to weight the received signal by multiplying the received signal by one of the common set of weighting factors or individual set of weighting factor; and a demodulator configured to demodulate the weighted signal.</p> |
