The OFDM Modulator block operation sequence is implemented using these blocks: Ready Generator, Symbol Formation, Sample Repeater, IFFT, FFT Shifter, Down Sampler, CP Addition, and Windowing. The windowing feature is supported for scalar and vector inputs. The parameters shown in this figure configu...

基于上述推导过程, 我们认为IFFT只是一个快速实现OFDM信号调制的算法, 生成OFDM基带信号可以不选择此种方式, 这也是为什么有些论文会把这一步叫做OFDMA Modulator, 而不是直接说Inverse Discrete Fourier Transform本质上OFDM基带信号是时域的多载波调幅波形,但在实际通信工程开发中,我们仍然习惯性地将IFFT前后区分为频域数...

Refer to the comm.OFDMModulator System object™ which can also be used to implement the CP-OFDM modulation. F-OFDM Receiver with No Channel The example next highlights the basic receive processing for F-OFDM for a single OFDM symbol. The received signal is passed through a matched filter, ...
TheLTE OFDM Modulatorblock implements an algorithm for modulating LTE resource grid samples specified by LTE standard TS 36.212[1]. The block uses an orthogonal frequency-division multiplexing (OFDM) mechanism in its operation and converts the resource grid input samples to an equivalent time-domain...
When the input continuous-wave (CW) optical power to the optical modulator is fixed, the output optical power of four band signal would be lower than the two band signal; thus, the receiver sensitivity would be lower in the case of four band signal. As shown in Fig. 1, the first part...
