Hi, Gurus,
In power cable failure detection, using a ring to receive patial discharge signal. The receiving band is about 3M~30MHz.
So reversly, i think it is possible to use the ring to transmit 3M~30MHz signal over the cable, thus forming a telecomm TX/RX system.
The system has the following spec:
1. Not using any cable core.
2. No need to destroy the cable.
3. Just use a ring to embrace over the power cable.
Then problem is:
1. Is it possible?
2. If using 20MHz as carrier, and using OFDM & veterbi decoders etc, how far it can transmit?
Best,
Tony Liu
