This is referred to as being'narrowband'. If the signal bandwidth is larger, then variations must be consideredover the band of transmission. This is referred to as 'wideband'. It is typical for highdata rate systems, such as video links and microwave systems. For the sake of claritywe will also differentiate frequency hopping systems, which cover wide frequenciesbut which may have the characteristics of broadband or narrowband systems.We will next consider narrowband signal and their characteristics before looking atother types of transmission. In this discussion, we will introduce the concept of fastfading and its effects on radio system performance.3.2 Narrowband Signals'Narrowband' signals are those that have a narrow bandwidth compared to theirtransmission frequency. Because of this, their propagation is considered in a singlecalculation that assumes that propagation is consistent across the bandwidth and alsothat fading characteristics are correlated. Historically, most transmissions for radiocommunications have been nalTowband in nature and their bandwidth has been set bythe modulation scheme selected or, in digital systems, according to the gross bit rate.By contrast, wideband signals have been more common in modem systems and insome of these the transmission bandwidth is wider than that necessary for thetransmission of the base information. It is instead combined with a higher rate code
