Delay hopped transmitted reference experimental results

This paper describes the experimental hardware design and implementation for a delay hopped transmitted reference communication system. The hardware is designed to generate the delay hopped transmitted reference signal for a number of experimental conditions. It can be used either in an ultra wideband pulse mode, ultra wideband noise mode, or in a narrowband mode. We use the experimental hardware setup to conduct link experiments with a delay hopped transmitted reference communication system. Experiments were conducted in an indoor multipath environment to test the viability of delay hopped transmitted reference for short-range indoor communications. The experimental results presented demonstrate that this modulation format is capable of transmitting data short range indoors without line of sight transmission path with minimal transmitted RF power.
