A. The amount of bandwidth allotted to each channel in a communications system that transmits multiple frequencies such as fiber optics . It is measured as the spacing between center frequencies (or wavelengths) of adjacent channels.
Read moreWhat is channel spacing in frequency?
Channel spacing, also known as bandwidth, is a term used in radio frequency planning. It describes the frequency difference between adjacent allocations in a frequency plan .
Read moreHow OFDM is used in LTE?
LTE uses a pre-coded version of OFDM called Single Carrier Frequency Division Multiple Access (SC-FDMA) in the uplink . This is to compensate for a drawback with normal OFDM, which has a very high Peak to Average Power Ratio (PAPR).
Read moreWhat is OFDM symbol in LTE?
One of the key elements of LTE is the use of OFDM (Orthogonal Frequency Division Multiplex ) as the signal bearer, as well as OFDM’s associated access schemes, OFDMA (Orthogonal Frequency Division Multiple Access) and SC-FDMA (Single Carrier Frequency Division Multiple Access).
Read moreWhat is LTE OFDM?
Orthogonal frequency-division multiplexing (OFDM), is a frequency-division multiplexing (FDM) scheme used as a digital multi-carrier modulation method . OFDM meets the LTE requirement for spectrum flexibility and enables cost-efficient solutions for very wide carriers with high peak rates.
Read moreIs LTE digital or analog?
This is the most exciting time in the mobile industry since the switchover from analog to digital back in the early 1990s. LTE represents a paradigm shift from hybrid voice and data networks to data-only networks.
Read moreWhat is modulation in mobile networks?
Modulation is a process of mixing signals with a sinusoid to produce a new form of signals . The newly produced signal has certain benefits over an un-modulated signal. Mixing of low-frequency signal with a high-frequency carrier signal is called Modulation.
