How is OFDM modulated?
OFDM takes the serial data to be transmitted and divides it up into many slower serial streams each of which is modulated onto one of multiple subcarriers. There may be as few as 40 subcarriers or many thousands. The subcarriers are spaced from one another by an amount that makes them orthogonal to one another.
How is OFDM implemented?
In a digitally implemented OFDM system, the input bits are grouped and mapped to source data symbols that are a complex number representing the modulation constellation point (e.g., the BPSKBinary phase shift keying - A type of phase modulation using 2 distinct carrier phases to signal ones and zeros. or QAM symbols ...
What is OFDM modulator?
The OFDM Modulator Baseband block applies Orthogonal Frequency Division Multiplexing modulation to an incoming data signal. The output is a baseband representation of the OFDM modulated signal.
How to generate OFDM signal?
Generate OFDM Modulated Waveform for Extended Cyclic Prefix
Generate a waveform by performing OFDM modulation of a resource array that contains physical downlink shared channel (PDSCH) demodulation reference signal (DM-RS) symbols. Set carrier configuration parameters, specifying a subcarrier spacing of 60 kHz.
