OFDM implementation in Simulink
显示 更早的评论
I am implementing OFDM Transmitter using QPSK Modulation. I am having trouble adding cyclic prefix to OFDM symbols as there is no predefined cyclic prefix. in addition what should be the parameters of it.

Create a cyclic prefix extension to the serial IFFT symbols with the help of Selector and Vector Concatenate blocks (extract from the end and append to the start) where the length of the cyclic prefix should be equal to the number of channel taps in the wireless channel model in the simulation.
Also, refer the documentation to know about different parameters considered in the transmission.
