What is complex baseband?
Key focus: Complex Baseband Equivalent Models are behavioral models that simplify the simulation, saves computation memory requirements and run time.
What is an optimum receiver and what is it optimized for?
Optimal Receiver: An optimal receiver is one that is designed to minimize the probability that a decision error occurs. There exists no other receiver structure that can provide a lower probability of error.
What is the complex envelope?
The complex envelope is just the low-pass part of the analytic signal. The analytic signal low-pass signal has been multiplied by the complex exponential at the carrier frequency.
What is equivalent baseband signal?
xE(t) is known as the equivalent baseband representation of the signal. It's really just the difference between the signal and the unmodulated carrier frequency, expressed in complex terms.
