Spectrum and Time Waveforms of a Multiband OFDM UWB Signal (1 minutes, 34 seconds)

Orthogonal Frequency Division Multiplexing (OFDM) is used in many wireless formats and it is also one of the modulation choices for UWB technology. In an OFDM signal, the input data is split into individual blocks, called symbols. The data is then spread over many sub-carriers to make it more resistant to fading. In a multiband OFDM radio, there is an added complexity – the signal changes frequency between every OFDM symbol. This means the receiver has to first synchronize to the frequency hopping before it can recover the remainder of the packet. This video uses the 89600 Series vector signal analysis software to show you how to recognize the different sections of a UWB signal burst using power and spectrum patterns. These and related measurements can help resolve basic interoperability problems, identify the cause of spectrum mask failures and check for amplitude compression in the transmitter or receiver circuits.
