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.
5G NR (5G New Radio) [1] is a radio access technology (RAT) ... The length of the cyclic prefix is inversely proportional to the subcarrier spacing. It is 4.7 μs ...

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 ...
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
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 ...
The annual Senior Bowl is set for Saturday in Mobile, Alabama.. A lead-up of practices sets up the game throughout the week to give 120 or more of the top draft-eligible prospects to showcase ...
DECT-2020, also called NR+, is a radio standard by ETSI for the DECT bands worldwide. [1] [2] The standard was designed to meet a subset of the ITU IMT-2020 5G requirements that are applicable to IOT and Industrial internet of things. [3]
