How to implement partial band noise jamming in matlab?

I am intended to implement communications schemes in the presence of jammming. So how can i implement jaming in matlab?

[Merged information from duplicate question]

i am doing a project in simulation and evaluation of different digtal modulation shemes in the presence of jamming. so i need to know how can i implement partial band noise jamming in awgn channel.

Did you get the code?

I think it is too late, but I hope it helps someone who refer to this question later.

As you use Bit Error Analysis Tool.

You need the proper coefficient for Eb/No which is defined as the normalized signal-to-noise ratio. For an instance, there are solutions for QASK, QPSK Modulations as follows:

I found the answer from the below article:

Coherent Detection of Frequency-Hopped Quadrature Modulations in the Presence of Jamming-Part I: QPSK and QASK Modulations, the authors are MARVIN K. SIMON, FELLOW, IEEE, AND ANDREAS POLYDOROS , and article is from IEEE TRANSACTIONS ON COMMUNICATIONS, VOL. COM-29, NO. 11, NOVEMBER 1981.
