  2. Carrier frequency offset - Wikipedia

    en.wikipedia.org/wiki/Carrier_frequency_offset

    The received signal also suffers from sampling clock offset (SCO), which may cause a gradual drift of the safe DFT window in addition to extra phase shift in the received frequency-domain signals. In frame-based OFDM systems, both the residual CFO tracking and the SCO tracking are inevitable, because the receiver may operate for a long period ...

    The signal would split with the help of four filters () for k =0,1,2,3 into 4 bands of the same bandwidths (In the analysis bank) and then each sub-signal is decimated by a factor of 4. In each band by dividing the signal in each band, we would have different signal characteristics. In synthesis section the filter will reconstruct the original ...

  4. Non-orthogonal frequency-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Non-orthogonal_frequency...

    An N-OFDM carrier signal is the sum of a number of not-orthogonal subcarriers, with baseband data on each subcarrier being independently modulated commonly using some type of quadrature amplitude modulation (QAM) or phase-shift keying (PSK). This composite baseband signal is typically used to modulate a main RF carrier.

  5. Carrier recovery - Wikipedia

    en.wikipedia.org/wiki/Carrier_recovery

    In the transmitter of a communications carrier system, a carrier wave is modulated by a baseband signal. At the receiver, the baseband information is extracted from the incoming modulated waveform. In an ideal communications system, the carrier signal oscillators of the transmitter and receiver would be perfectly matched in frequency and phase ...

  6. Node-to-node data transfer - Wikipedia

    en.wikipedia.org/wiki/Node-to-node_data_transfer

    Multiplexing, the transmission of multiple data signals in one frequency band, on different carrier frequencies. Smaller, more directional antennas; Carrier signals are usually high frequency electromagnetic waves. Examples of modulation include: amplitude modulation; frequency modulation; Phase-shift keying

  7. Baseband - Wikipedia

    en.wikipedia.org/wiki/Baseband

    A baseband channel or lowpass channel (or system, or network) is a communication channel that can transfer frequencies that are very near zero. [4] Examples are serial cables and local area networks (LANs), as opposed to passband channels such as radio frequency channels and passband filtered wires of the analog telephone network.

  8. Passband - Wikipedia

    en.wikipedia.org/wiki/Passband

    The passband of a receiver is the range of frequencies it can receive when it is tuned into the desired frequency (channel). A bandpass-filtered signal (that is, a signal with energy only in a passband), is known as a bandpass signal, in contrast to a baseband signal. [1] The bandpass filter usually has two band-stop filters.

  9. Orthogonal frequency-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Orthogonal_frequency...

    If no guard interval was applied, this would result in a base band complex valued signal with a sample rate of 1 MHz, which would require a baseband bandwidth of 0.5 MHz according to Nyquist. However, the passband RF signal is produced by multiplying the baseband signal with a carrier waveform (i.e., double-sideband quadrature amplitude ...
