Coherent Detection of Frequency-Hopped Quadrature Modulations in the Presence of Jamming--Part II: QPR Class I Modulation

This paper considers the performance of QPR in the presence of the identical jamming postulated in Part I. Although a QPR system employs a single sample detector in its receiver, while QASK (or QPSK) requires a matched-filter type of receiver., it is shown that the coherent detection performances of the two in the presence of the intentional jammer have definite similarities.
