Abstract:

The utilization of the spectrum can be improved by using the technologies of co-time co-frequency full duplex (CCFD) in theory, which has attracted many attentions by researchers. Measurements and characterizations are rarely involved at indoor single antenna selfinterference channel of CCFD. Measurements and analyses are performed at 2.6 GHz under typical indoor environment with channel sounder based on vector network analyzer. By analyzing the measurement data, the empirical channel characteristics such as the RMS delay spread and the coherence bandwidth have been extracted. The impacts of the feed line of antenna on the rootmeansquare (RMS) delay are studied. Results show that the statistics of RMS delay follow lognormal distribution. The RMS delay increases with increasing the length of the feed line. The statistics of coherence bandwidth follow normal distribution. It has been confirmed that an inverse relation between the coherence bandwidth and the RMS delay spread.
