OFDM DemodSCS

OFDM demodulation of the signal with the total distance between subcarriers.

blockType: OFDMDemodSCS

Path in the library:

/5G/OFDM DemodSCS

Description

After receiving the MIB, the block uses the total subcarrier distance and bandwidth to demodulate the OFDM frame. Adjusts the frequency of the phase compensation of the symbol using the introduced frequency shift. Adjusts the timing offset relative to the beginning of the first frame, if the frame offset is negative, the first frame is incomplete and adds leading zeros to the signal to align it to this frame. Determines the number of resource blocks and the distance between subcarriers for OFDM signal demodulation. Demodulates the received signal with the total distance between subcarriers.
