将labview的数据类型文件转换为matlab能够读取的数据类型(The LabVIEW data type file is converted to Matlab can read the data types )

Adaptive filtering constitutes one of the core technologies in digital signal processing and finds numerous application areas in science as well as in industry. Adaptive filtering techniques are used in a wide range of applications, including echo cancellation, adaptive equalization, adaptive noise cancellation, and adaptive beamforming. Acoustic echo cancellation is a common occurrence in today’s telecommunication systems. The signal interference caused by acoustic echo is distracting to users and causes a reduction in the quality of the communication. This paper focuses on the use of LMS and NLMS algorithms to reduce this unwanted echo, thus increasing communication quality.

该程序简单的仿真了OFDM系统，包括信号的产生，映射，调制，加噪，解调(The program is simple simulation of the OFDM system, including signal generation, mapping, modulation, noise, demodulation)
