Gaussian pulse for bit transmission

I want to simulate by using Matlab Gaussian pulse for one-bit transmission in wireless network with 100-fs-long duration and 1pJ energy and

1THz frequency and the average ratio of bit “1” in a packet is 50%.

How I can simulate this in Matlab? Is there any built-in function to simulate this?

There are many simulators.

What channel model?

What's one-bit transmission?

Binary modulation? ASK, with Gaussian pulse shape?
