WebFrequency units can be expressed in number of subcarriers or resource blocks. For instance, a 5 MHz downlink signal could be described as 25 resource blocks wide or 301 subcarriers wide (DC subcarrier is not included in a resource block). . The underlying data carrier for an LTE frame is the resource element (RE). The resource element, which is 1 subcarrier x 1 … WebJan 6, 2024 · In addition, the beginning and ending portions of the symbol period are attenuated. Thus, ISI is reduced by providing a pseudo-guard interval which attenuates signals from multi-path reflections. As a result, inter symbol interference (ISI) can be reduced while still limiting each channel to a specified bandwidth.
