Hello my friends,

My question is that how can smart antennas able to adapt itself in order to smooting better to a number of user equipment at the same time in UMTS?


Thank you all after now.

Best regards,

Eray

Smart antennas consist of an antenna array, combined with signal processing in both space and time. Spatial processing leads to more degrees of freedom in the system design, which can help to improve the overall performance of the system.

Smart antenna, when used appropriated, help in improving the system performance by increasing channel capacity and spectrum efficiency, extending range coverage by steering multiple beams to track many mobiles.

Smart antenna systems are usually categorized as switched beamer, and adaptive array systems
A switched beam antenna system consists of several highly directive, fixed, pre-defined beams, and choose the beam which gives the best SNR. . A switch is used to select the best beam to receive a particular signal.
In adaptive array systems, the weights are adjusted by some means using available information derived from the array output.

applications of switched beam antennas

Ya!

By Sharing the Knowledge we can improve, i am not expertise but i have learnt so many things by this way.....

By the way do you know any person working on WCDMA?Currently I am getting error in simulation of WCDMA Rake Receiver. Hence i can contact him.

hi all.
i am researching on smart antenna too, i want to see the benefits of smart antenna in wireless communictian, i have a question: in the smart antenna system, beamforming network is first or demodulation and decoding??? i use cdma system for simulation.
