Web9 Jun 2024 · a narrow frequency band. In time-hopping (TH-)CDMA, a pseudo-noise sequence deﬁnes the transmission moment for the various users, which can be viewed as sparse CDMA when used in an ultra-wideband impulse communication system. In this case the sparse time-hopping sequences reduces collisions between transmissions. WebThe well-known binary Walsh sequences or variable- length orthogonal sequences have perfect orthogonality at zero time delay, and are ideal forsynchronous CDMA(S- CDMA) systems, such as the forward link transmission.
