⛄ 内容介绍

近年来,随着移动通信的迅速发展,用户急剧增加,移动通信的频谱资源日益紧张,多址干扰、共信道干扰以及多径衰落的影响限制了信道容量和通信质量的进一步提高。智能天线和空间滤波为这些问题的解决带来了新的思路。智能天线技术利用信号的空间特征——到达角来克服这些因素的影响,在保证一定的通信质量的前提下,能够提高覆盖范围,增加系统容量。 本文基于MVDR LCEC GSC PCI MWF EC PCA_MVB多种算法实现自适应波束生成​。

⛄ 部分代码

function varargout = algrithem_database(varargin)

% ALGRITHEM_DATABASE M-file for algrithem_database.fig

%      ALGRITHEM_DATABASE, by itself, creates a new ALGRITHEM_DATABASE or raises the existing

%      singleton*.

%

%      H = ALGRITHEM_DATABASE returns the handle to a new ALGRITHEM_DATABASE or the handle to

%      the existing singleton*.

%

%      ALGRITHEM_DATABASE('CALLBACK',hObject,eventData,handles,...) calls the local

%      function named CALLBACK in ALGRITHEM_DATABASE.M with the given input arguments.

%

%      ALGRITHEM_DATABASE('Property','Value',...) creates a new ALGRITHEM_DATABASE or raises the

%      existing singleton*.  Starting from the left, property value pairs are

%      applied to the GUI before algrithem_database_OpeningFunction gets called.  An

%      unrecognized property name or invalid value makes property application

%      stop.  All inputs are passed to algrithem_database_OpeningFcn via varargin.

%

%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one

%      instance to run (singleton)".
