Abstract: A base station for a wireless communications system operating in an unlicensed target band of a wireless medium includes a receiver configured to wirelessly (i) receive non-cooperative carrier data within the target band from a user equipment, and (ii) detect an operation of at least one spread spectrum channel within the target band. The station further includes a transmitter configured to wirelessly send non-cooperative carrier data within the target band to the user equipment, a memory configured to store computer-executable instructions, and a processor configured to (i) execute the computer-executable instructions, (ii) determine, based on the detection operation of the receiver, at least one sequence of the at least one spread spectrum channel, and (iii) perform at least one corrective action to mitigate interference between the transmitter and an operation of the at least one spread spectrum channel based on the determination of the at least one sequence.

Abstract: A method for transmitting data via a coaxial electrical cable includes (a) converting symbols of each input data stream of a plurality of parallel input data streams from digital form to analog form, (b) individually filtering symbols of each input data stream, (c) transforming symbols of each input data stream from a first frequency-domain to a first time-domain, to generate parallel first time-domain samples, (d) converting the first time-domain samples to a serial multi-carrier signal, and (e) injecting the multi-carrier signal onto the coaxial electrical cable.
