WebFig. 3: Spread Spectrum (SS) Signals B. Spread Spectrum (SS) Spread Spectrum is an alternative technique to UNB for industrial IoT systems, which employs wideband (noise-like signals) to transmit the data and spread the data signal over a bandwidth which is much larger than the bandwidth of an actual data signal. Unlike in narrowband, where data is Web5 apr. 2010 · Delay spread is the time spread between the arrival of the first and last multi path signal seen by the receiver. In a digital system, the delay spread can lead to Inter-Symbol Interference (ISI). ... (Orthogonal Frequency Division Multiplexing) 5.
