Abstract:
A coaxial network communication node receives multimedia content with one or more other nodes in a Multimedia over Coax Alliance (MoCA®) coaxial network. The node determines a delay-spread of a coaxial channel based on a probe received from a transmitting node during a link-maintenance operation (LMO) cycle. The probe is stored and reused during the LMO until the channel-shortening TEQ filter converges. The node configures a channel-shortening time-domain equalizer (TEQ) filter to effectively shorten the channel and instructs the transmitting node to shorten a length of a cyclic prefix for subsequent packet-based transmissions.
