多载波调制(Multicarrier Modulation)采用了多个载波信号。它把数据流分解为若干个子数据流，从而使子数据流具有低得多的传输比特速率，利用这些数据分别去调制若干个载波。所以，在多载波调制信道中，数据传输速率相对较低，码元周期加长，只要时延扩展与码元周期相比小于一定的比值，就不会造成码间干扰。因而多载波调制对于信道的时间弥散性不敏感。多载波调制可以通过多种技术途径来实现，如多音实现(Multitone Realization)、正交多载波调制(OFDM)、MC-CDMA和编码MCM(Coded MCM)。其中，OFDM可以抵抗多径干扰，是当前研究的一个热点。(Multi carrier modulation (Multicarrier Modulation) uses multiple carrier signal. It decomposes a data stream into a plurality of sub data stream, so that the sub data stream transmission bit rate is much lower, respectively to a plurality of carrier modulation using these data. )

SEEP5( Property , Value ,...) creates a new SEEP5 or raises the existing singleton*. Starting the left, property value pairs are applied to the GUI before seep5_OpeningFunction gets called. An unrecognized property name or invalid value makes property application stop. All inputs are passed to seep5_OpeningFcn via varargin.

独立向量分析（IVA）是对独立成分分析（ICA）算法的一种扩展，将ICA中的单变量成分扩展为多维变量成分，可有效避免卷积盲源分离过程中的排序模糊性问题。(Independent vector analysis (IVA), a multivariate extension of independent component analysis, tackles the convolutedly mixed blind source separation (BSS) problem in a way to avoid the permutation problem by employing a multivariate source prior of the short-time Fourier transform (STFT) components. )

本代码是宽带DOA估计matlab代码，信号源是BPSK信号，采用一般线性阵列或均匀线性阵列接收，共涉及频谱已知和未知两种情况。并且各部分均单独编写了m函数。(This code is used to conduct DOA of a broadband signal. The signal source is BPSK, with a general linear array or uniform linear array. Each of these cases includes two kinds of known and unknown spectrum. And, an M function is written separately in each part. )
