Study on the Broadcast Beam-forming of Smart Antenna by the Method of Baseband-Amplitude-Weighting
In reality,wireless communication channels are designed to serve for multiple users while muitipath propagation interference (MPI) and other problems are deteriorating the quality of service,especially when modern wireless communication demands higher data rate giving that less and less radio Spectrum resources are available.Compared to conventional techniques trying to solve the related problems,smart antenna (SA) may have shed new light on the solutions of these issues.The forming of broadcast beam of SA is studied in this paper.Firstly,the mathematical formulas for the forming of directional broadcast beam by the method of baseband-amplitude-weighting are derived,according to which the corresponding circuit diagram is given.Then the forming method for broadcast beam for SA by combining several directional radio beams is presented.Moreover,the computer simulation results of SA with 6 array elements are provided to demonstrate the accuracy and achievability of this beam-forming method.
