Latest Patents

Chien's latest patents include innovative methods for downstream time domain based adaptive modulation for DOCSIS based applications. In one of his patents, he describes a system where data is transmitted over a downstream channel at varying throughput rates. This system assigns throughput rates to data destined for each subscriber based on the downstream signal quality. The downstream data is parsed to extract data packets, which are then organized into packet queues. These queues represent the bandwidth efficiency that can be tolerated by specific subscribers, adapting to the current signal quality at their locations. Another patent elaborates on a similar concept, focusing on the parsing of DOCSIS MAC data to optimize data transmission for satellite modems.
