RF front end digital beamformer for smart antenna array - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.


 Post subject: RF front end digital beamformer for smart antenna array
Posted: Mon Jul 19, 2004 11:50 am 
Greetings all,

I'm kinda new in this area, and was given a task to intergrate the RF front-end digital Beamformer circuit. my question is how do i do that, what are the paramters that i should take consider of? does the word intergrate means i have to convert the signal in frequency domain into time domain? is there any book reference that i can refer to regarding beamforming network? I just need to know how to start with this project? Many thanks.

cheers

Beamforming is usually done with an Array or antennas sperated by Quater wavelength and applying amplitude and phase shifts to the signal so that the directivity of the array can be rotated. You can do complex multiplications in digital domain to achieve this.

Greetings Elfa:

I just picked up the August 2004 edition of Microwave Journal and see there is a major feature article on beam-forming antennas that you might be interested in reading.

Here's a link to the article, but you might need to sign in to access it:

check out
Digital beamforming in Wireless Communications
John Litva and Titus Kwok-Yeung Lo
Im currently doing a project on it as well.

Basically try reading up on
Adaptive beamforming networks
since u need smart arrays and a digital beamforming network.
