how ads simulate communication system including rf and dsp

i am a dsp disigner. but now i deed to simulate rf communication system including adc,dac and digital modulation.

waht book i should read? i have read razavi and h.lee about rf.

Could anyone give me a practical mixed design example (i mean a design includes RF and DSP) based on @DS?

how to simulate system including adc and rf receiver?

Ptolemy is the ungine that is used by @DS to simulate communication systems.
There is the possibility to use co-simulations with blocks at circuit level (using envelope in the circuit level block).
There's alot of literature available, look at elektroda or directly in @DS manual or in @gilent web site.
I hope it can help.

thank Mazz
i want to know that is it practical to simulate AD control in ads when using ptolemy?

it is my target also. is there any example for simulation in @ds including adc ,rf and DSP arithmetic.

I've taken an exampple on ADC:

This example demonstrates the Timed ADC and DAC models in Advanced Design System through a basic digital audio codec application. These models are suitable for the modeling of ideal or non-ideal conversion in signal processing applications.

It's an @DS project. rename it with extension zap and open directly with @DS
I hope it can help.

ADS can simulate the RF and DSP with the tools named co-simulation. for example if you want to simulate one system contains DSP part and RF mixers,you cna use co-simulation to simulate the spectrum and power output. I have done some work at this aspect and I think there are problem about the accuracy of simulation.
you can refer to the example or search them from the "help" documents/
