Claim of US Patent No. 10,181,972

1. A system for communicating between nodes in a mobile ad hoc network, the system comprising:a plurality of nodes in a mobile ad hoc network, wherein at least a first node in the plurality of nodes is configured to communicate with a second node in the plurality of nodes using both code division multiple access (CDMA) and frequency division duplexing (FDD);
wherein the communication is coded on the first node prior to transmission to the second node, the coding including applying direct sequence spread spectrum (DSSS) modulation to a transmission signal at a specified bit rate over a specified spectrum, the DSSS coding being applied in accordance with a processing gain which spreads the spectrum relative to the bit rate of the transmission, wherein the spectrum is spread at a factor of at least 1,000 times, such that bandwidth for the transmission is at least 1,000 times greater than the transmission bit rate; and
wherein the coded communication is transmitted over a specified frequency band allocated to the first node over which the first node transmits data and over which the second node receives the data.
