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.
How to generate OFDM signal in Matlab?
waveform = hMod( insignal ) applies OFDM modulation the specified baseband signal and returns the modulated OFDM baseband signal. waveform = hMod( data , pilot ) assigns the pilot signal, pilot , into the frequency subcarriers specified by the PilotCarrierIndices property value of the hMod system object.
What is a OFDM symbol?
Orthogonal frequency division multiplexing (OFDM) takes a digital information signal with bit rate Rb, maps n-bit words on to M = 2n symbols (each symbol being a complex number representing the amplitude and phase of an M-ary modulation scheme), splits the resulting symbol stream (rate Rs = Rb/n) into N parallel ...
What is OFDM symbol in LTE?
The OFDM symbols are grouped into resource blocks. The resource blocks have a total size of 180kHz in the frequency domain and 0.5ms in the time domain. Each 1ms Transmission Time Interval (TTI) consists of two slots (Tslot). Each user is allocated a number of so-called resource blocks in the time.
