调频高速数据广播

Frequency Modulation High Speed Data Broadcasting

本广介绍一种“W码”的数据信号处理新技术。“W码”具有传输速率高、抗干扰能力强、解码电路简单的特点。“W码”技术可应用于调频SCA信道的数据广播,也可在播出非立体声节目时,在L-R信道进行数据广播,该系统与现有调频广播系统完全兼容。

This thesis introduces a new technique of data disposing of W - code. W - code has high transmitting rate, strong resistting interference and simple decode circuit. W - code is used data broadcasting in FM SCA channel; when broadcasting monophonic program, it can be used in L- R channel, too. The system is compatible with the conventional FM broadcasting system.
