Single-channel, full-time full-duplex wireless signal transmission system

A wireless single-frequency-channel, full-duplex, full-time transmit and receive communication node comprising:

• a) an antenna that transmits a transmit signal over a wireless transmit channel and that receives a receive signal over a wireless receive channel;
• b) a communications processor comprising:
• i) a first port electrically coupled to the antenna;
• ii) a second port electrically coupled to a transmit path, the transmit path connecting the second port to the first port;
• and
• iii) a third port electrically coupled to a receive path, the receive path connecting the first port to the third port,
• wherein the communications processor is configured to pass the transmit signal in the transmit path to the first port and is configured to pass the receive signal in the receive path from the first port to the third port such that the transmit signal and the receive signal occupy a same frequency channel and operate simultaneously in a same time slot;
• and
• c) a channel state information processor electrically coupled to the receive path, the channel state information processor calculating up-link channel state information based on the receive signal such that channel state information is measured and processed to determine the up-link channel state information in a time slot, while the transmit signal and the receive signal occupy the same frequency channel and operate simultaneously in the same time slot.
