Optimizing Link Performance, Cost and Interchangeability by Predicting Residual BER: Part II - Nonlinearity and System Budgeting

This is the second part of a two-part tutorial on residual BER prediction for cost optimization of oscillator phase noise and power amplifier linearity. Today’s demanding digital modulations require a different type of analysis at ‘normal’ receive powe...
In part I, the economic case from the network operator’s perspective was reviewed and it was found that as operators improve their residual BER performance, their market space is expanded from simple voice applications to e-commerce transactions and other data traffic which demands ultra low error rates. Next, the...
