A study of jamming on QPSK modulation

As the increased use of digital communication continues, the communication environment becomes more challenging than before. QPSK Modulation is widely used as a current digital communication method, in particular on the wireless communication network and high-performance communication links. The purpose of this thesis is to follow with a systematical study on the digital communication system , modulation methods and jamming methods, from the simulated result, estimate the performance for different types of jamming which affect QPSK modulation, determine the performance of each jamming schemes in a particular condition, and how the limited jamming signal powerwill be used effectively. And this thesis has estimated the effectiveness of one jamming (single-tone jamming and multi-tone jamming) that affect the QPSK Modulation from comparing the bit error rate (BER) of the communication system.
