Numerology µ=0, Normal Cyclic Prefix mode. For symbols 0 and 7 within a slot in Normal cyclic prefix mode, $10240 T_c$ seconds are copied. Abstract: Although orthogonal frequency-division multiplexing (OFDM) is a widely accepted waveform in many standards and is expected to keep its dominance in future 5G systems with various types of parameterized waveforms, its performance in terms of spectral efficiency as well as transmission latency is usually degraded due to the excessive usage of cyclic prefix (CP). I know that in 5G, FBMC does not use CP (cyclic prefix) while F_OFDM has CP, but If I'm suppose to choose one which one I should choose and why?

Numerology (3GPP term) is defined by Sub Carrier Spacing (SCS) and Cyclic Prefix (CP). The preamble consists of two parts cyclic prefix (CP) and Preamble Sequence. In 5G NR, there are 13 types of preamble format supported known as Format 0, Format 1, Format 2,Format 3,Format A1,Format A2,Format A3,Forma t B1, Format B2, Format B3, Format B4, Format C0, Format C1. These 13 types of preamble format can be grouped into two categories: The Bandwidth is divided into many narrow tones, where the tones are basically orthogonal to each other with no Inter-Symbol Interference (ISI) by Cyclic Prefix. In OFDM, the bandwidth can be allocated more flexibly by scaling the subcarriers, and the high-rate data is distributed onto many low-rate channels. LTE uses Cyclic-Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveform for downlink transmissions and DFT-Spread OFDM for uplink transmissions. On the road to 5G, the mobile communications community has witnessed abundant waveform proposals for NR. Numerology, which determines sub-carrier spacing and cyclic prefix, is also an essential BWP configuration. Some allocation scenarios are illustrated in the figure.

Noise and time-variant effects are neglected. 18 Dec 2017 CUPS forms the basis of EPC architecture evolution for Service-Based Architecture for 5G Core Networks. More in another post soon.

What the CP does is to copy a small part of the initial information (hence the name prefix) to the end of each symbol (hence the name cyclic).

W-OFDM In W-OFDM, processing is performed at the beginning and end of each OFDM symbol after IFFT computation. A cyclic prefix (CP) and cyclic suffix (CS) are … Want to learn PYTHON and R projects for 5G Technology? Check out our NextGen 5G School!

5G. Frequency Modulation. Can We Do Without a Cyclic Prefix October 19, 2011 BER Performance , Channel Modeling , LTE , WiMAX Channel , Convolution , Cyclic Prefix , FIR , LTE , Rayleigh , WiMAX John (YA) Have you ever thought that Cyclic Prefix in OFDM is just a gimmick and we could do equally well by using a guard period i.e. a period of no transmission between two OFDM symbols.

Can we completely remove this cyclic prefix in 5G Waveform ? Cyclic Prefix OFDM: CP-OFDM The specific version of OFDM used in 5G NR downlink is cyclic prefix OFDM, CP-OFDM and it is the same waveform LTE has adopted for the downlink signal.

The remaining six symbols have a cyclic prefix of length TCP = 144 ⋅ Ts ≈ 4.7 μs. The reason for different CP length of the first symbol is to make the overall slot length in terms of time units divisible by 15360.
