Principal Component-Based Approach for Profile Optimization Algorithms in DOCSIS 3.1.
IEEE Transactions on Network and Service Management(2018)
摘要
Data over cable service interface specification (DOCSIS) introduced the possibility of a variable bit-loading over the subcarriers within a channel in its release DOCSIS 3.1. This variable bit-loading will improve the data rates. However, to limit the encoding processing overhead, the concept of profiles was introduced. Each profile defines the modulation per subcarrier for a given channel while t...
