The Error Era: Rethinking Codeword Calculation with OFDM and SC-QAM

Mia Colabrese2024-06-06T13:43:07-04:00June 6th, 2024|

In our DOCSIS networks, accurately calculating uncorrectable codeword errors is essential for monitoring and maintaining network integrity. These errors, which cannot be corrected by the system’s error-correction algorithms, are known as uncorrectable codewords. The frequency and occurrence of uncorrectable codeword errors can signal physical or network impairments that adversely affect a subscriber’s quality of experience (QoE). When the percentage of these errors surpasses 1%, subscribers typically experience noticeable declines in service quality, which may include slower Internet speeds, disruptions to real-time services like voice and gaming, or even
