摘要

针对多输入单输出（MISO

multiple input single output）通信系统的STBC-OFDM信号盲识别问题，提出基于OFDM块的改进Kolmogorov-Smirnov (K-S)检测方法。该方法首先对MISO通信系统的STBC-OFDM信号建模；然后利用STBC-OFDM信号编码矩阵的相关性，构造不同时延向量下STBC-OFDM接收信号OFDM块的经验函数作为特征函数；最后通过改进K-S检测方法检验经验分布函数之间的距离盲识别STBC-OFDM信号。该方法不需要噪声信息、调制信息和信道系数，适合非合作通信场合。理论分析和实验验证了该方法的可行性。

Abstract

Aiming at the problem that existed blind classification of STBC-OFDM in multiple input single output (MISO) communication system

an efficient method for blind classification of space-time block coded orthogonal frequency-division multiplexing (STBC-OFDM) signals based on modified Kolmogorov-Smirnov (K-S) test was proposed

when a single receiver antenna was employed at the receiver.Firstly

the model of received STBC-OFDM signals in MISO systems was given.Secondly

with the correlation of the coding matrix of STBC-OFDM signals

and the discrimination features function provided by the empirical cumulative distribution (CDFs) of the received OFDM blocks was constructed.Finally

the distance between CDFs was tested by the two-sample K-S test

which could blindly classify the STBC-OFDM signals.The proposed algorithm didn't need the estimation of channel

noise statistics and modulation type

and consequently

was well suited for non-cooperative communication context.Theoretical analysis and experimental verify its validity.
