Customizable DOCSIS 3.1/OFDM test tools bundled with true spectrum analyzer for quickly verifying and troubleshooting next generation HFC networks SAN JOSE, Calif.–(BUSINESS WIRE)–October 19, 2017– ...

Virtually all major new wireless technologies, including WiMAX and LTE, are based on orthogonal frequency-division multiplexing (OFDM), which has emerged as the wireless spectral efficiency leader.

OFDM is the emerging technology for high data rates in various standards. In this project, a novel architecture has been proposed both in the transmitter and the receiver end, in order to provide a ...

WASHINGTON: A newly formed broadcast group is lobbying federal regulators bent on taking broadcast spectrum for broadband to consider alternatives. The group demonstrated how orthogonal frequency ...
