Measuring characteristics of microwave mobile channels

Introduction to spread-spectrum antimultipath techniques and their application to urban digital radio

“…As indicated by (10), the outputs of the matched filters In Fig. 18(a), we have shown a case in which there is no intersymbol.…”

“…Wideband experimental data that ch.iracterize individual paths are less common [51, [10], 1191, 133), [371. In order to resolve two paths in such measurements, thc2 sounding sig:inl'5t bandwidth must he larger than the rec iprocal of tt.…”

“…(b) The sidelobe levels of all outputs is increased, since (10) shows the addition of multipath contributions.…”

“…Suppose that the sample of the kth output envelope at time T+t k is Xtk* (In the absence of noise Xtk = ez(tk) as given by (10).) Then, if all path strengths ak are known, the optimal combining of the samples is…”
