  2. Cyclic prefix - Wikipedia

    en.wikipedia.org/wiki/Cyclic_prefix

    For the cyclic prefix to serve its objectives, it must have a length at least equal to the length of the multipath channel. The concept of a cyclic prefix is traditionally associated with OFDM systems, however the cyclic prefix is now also used in single carrier systems to improve the robustness to multipath propagation.

  5. Numerology (wireless) - Wikipedia

    en.wikipedia.org/wiki/Numerology_(wireless)

    In wireless communication, the term numerology refers to "waveform parametrization, e.g., cyclic prefix, subcarrier spacing." [1] The waveform selection is subject to a set of real-world restrictions, so a practical mobile communication system (with signal propagation conditions that tend to vary significantly from one location to another), utilizes a set of different waveforms, or "multiple ...

  6. Single-carrier FDMA - Wikipedia

    en.wikipedia.org/wiki/Single-carrier_FDMA

    After removing the cyclic prefix at the receiver, a DFT is applied to arrive in the frequency domain, where a simple single-carrier frequency-domain-equalization (SC-FDE) scheme can be employed, followed by the IDFT operation. DFT: Discrete Fourier Transform; IDFT: Inverse Discrete Fourier Transform; CP: Cyclic Prefix; PS: Pulse Shaping

  7. MIMO-OFDM - Wikipedia

    en.wikipedia.org/wiki/MIMO-OFDM

    Multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) is the dominant air interface for 4G and 5G broadband wireless communications. It combines multiple-input, multiple-output technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into ...
