on second though for ami init onley one sample is required, with amplitued of
1/dt where dt is the sample_interval

Kumar,
For
robustness sake, can you please enumerate the values of an impulse response of
an ideal channel in the form of a rectangle/triangle with area 1.

1. that may depend
upon model implementation. for robustness sake i will provide a
rectangle/triangle with area of 1
2. the one half
clock period is based on the UI.

Hi, Experts;
I want to take a break from the flow discussion by asking two
questions.
1.
If the channel is perfect and its impulse response is a Dirac
delta function, what impulse data should be input to AMI_Init, a pulse (e.g.
rectangle or triangle) with area being 1, or a discrete data with 1 at t=0
and 0 at other time points?
2.
Section 3.2.2.2 states that “It is to be assumed that the input data signal is
sampled at exactly one half clock period after a clock time”. Does “clock
period” mean one UI or the time between two neighboring clock times returned
by GetWave?
I’d appreciate it if anyone can provide me clarification.
Thanks,
Fangyi
