Introduction
Rex Coldren is a notable inventor based in Phoenix, AZ (US), recognized for his contributions to communication technologies. He holds 2 patents that showcase his innovative approach to solving complex problems in the field.
Latest Patents
One of his latest patents is focused on full duplex cable communication. This invention describes a controller that performs several functions, including discovering a mapping between receive analogue to digital converters (RxADCs) of a full duplex node and cable modems connected to that node. The cable modems share a common communication bandwidth, and the invention also determines sounding groups by grouping cable modems mapped to the same RxADC into respective sounding groups. This innovation is significant as it helps identify potential interference among cable modems.
Another important patent by Rex Coldren is a method and apparatus for transmitting frequency shift key (FSK) data in a packetized format. This invention is directed towards using a new Real-Time Transport Protocol (RTP) payload type to transport FSK data, which is essential for voiceband data transmission outside of the voice RTP stream. This technique enhances data compression and minimizes the risk of packet loss for FSK data carried in-band.
