Digital Stepping Correlator in a Wideband Radio Channel Measurement System

This paper explains the realization and the performance of a digital stepping correlator in a wideband radio channel measurement system. Radio channel sounding is based on the estimation of the radio channel by use of maximum length sequence (m-sequence) as an effective sounding signal. Signal is detected using the stepping correlator receiver. The received signal is not converted to the baseba...

Accuracy of Relative Distance Measurement with Ultra Wideband System

Since very short pulse waves are transmitted, UWB systems have excellent accuracy in terms of distance measurement. In order to measure the distance between the terminals, the transmitted pulses have to be synchronized by a delay-lock-loop (DLL) in the receiver. In this paper the performance of the DLL is evaluated. Its performance depends the timing jitter between the local clocks of the termi...

Synchronization in a Wideband Optical Data Transmission System

An optical synchronization technique is described for the demultiplexer of a wideband optical data transmission system. In this system, the closely spaced optical pulses of interleaved PCM channels are “space sorted” by a coincidence detection technique using an optical reference waveform generated in the receiver. For synchronization of the reference waveform with a spatial waveform produced b...

An Optical Measurement System to Measure Velocity and Provide Shock Wave Pressure Diagrams

This paper introduces an optical measurement system for shock wave characteristics. The system works by mountinga metal plate attached to spring mounts against the shock wavefront. This set is sealed and can plot the shock wave pressure diagram by measuring plate's displacement, radiation and changing the reflection of light during shock wave conflict, and converting these optical data to volta...
