In OFDM and OFDMA PHY layers, the DC subcarrier is the subcarrier whose frequency is equal to the RF centre frequency of the transmitting station . It corresponds to frequency zero (Direct Current) if the FFT signal is not modulated.
Read moreWhat is subcarrier frequency?
A subcarrier is a secondary modulated signal frequency modulated into the main frequency (the carrier) to provide an additional channel of transmission . It allows for a single transmission to carry more than one separate signal.
Read moreWhy are there different subcarrier spacing in 5G?
Wider subcarrier spacing would provide better resistance to such increased Doppler shifts at higher frequency bands . Furthermore, 5G NR provides a flexible solution to support various applications by choosing an appropriate configuration. For example, when higher Δf is used, it results in a shorter slot duration.
Read moreWhat is subcarrier bandwidth in LTE?
Each subcarrier is able to carry data at a maximum rate of 15 ksps (kilosymbols per second) . This gives a 20 MHz bandwidth system a raw symbol rate of 18 Msps. In turn this is able to provide a raw data rate of 108 Mbps as each symbol using 64QAM is able to represent six bits.
Read moreHow high peak transmission rate is carried out by LTE?
Long Term Evolution (LTE), which evolved from conventional 3rd Generation Partnership Project (3GPP) systems, is expected to provide downlink and uplink peak data rates of over 100 Mbps and 50 Mbps, respectively.
Read moreHow can 5G NR efficiently increase the coverage?
But the higher frequencies also allow higher antenna gains to be generated without increasing physical antenna size. 5G can utilize these increased antenna gains through beamforming both at the transmitter and at the receiver , which helps mitigate the impact on coverage at higher frequencies.5 Kas 2018
Read moreWhat is peak data rate in 5G?
5G is faster than 4G. 5G can be significantly faster than 4G, delivering up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-second (Mbps) average data rates.
