    ABSTRACT: In this paper, the effect of multipath fading on the orthogonality of FH/MFSK communication systems is analyzed. A general expression of the orthognality loss factor D<sub>jn</sub> is derived for the case of multipath Rayleigh fading. Based on the expression, it is shown that the D<sub>jn</sub> is determined not only by the multipath delays, signal strength fading and synchronization time error, but also by the phase variations caused by multipath time delays. Numerical results demonstrate that the effects vary with different phase variations. This result will further affect BER performance of FH/MFSK systems.

    ABSTRACT: Based on the concept of the zero correlation zone (ZCZ), a class of frequency hopping (FH) sequences with the defined no hit zone (NHZ) property is presented. The NHZ FH spreading code sequences obtained are derived by mapping from the known ZCZ sequences, and may find applications in frequency-hopped CDMA systems to reduce or eliminate multipath and inter-user interferences.
