OFDM simulation for timing recovery

可以在Windows 平台和Linux 平台上编译，提供有关syncml开发的一系列API，包含一个综合 C 库，用于创建、发送、接收和解析 SyncML 消息。它支持 XML 和 WBXML 编码，还支持 HTTP（用于 Web 上的同步）、WSP（在 WAP 上使用）和 OBEX（在 IrDA 或蓝牙上使用）传输。-in the Windows platform and Linux compiler, the SyncML development of a series of API, includes a comprehensive C library for creating, sending, receiving and analytical SyncML news. It supports XML and WBXML coding, also supports HTTP (for Web synchronization), the WSP (in the use of WAP) and OBEX (IrDA or use Bluetooth) transmission.

In this simulink model , baseband binary detection is simulated .A rectangular pulse shaped signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The binary signal transmitted is recovered at the detector output.-In this simulink model , baseband binary detection is simulated .A rectangular pulse shaped signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The binary signal transmitted is recovered at the detector output.
