Hi,
I have implemented a system OFDM 2K with band of 8 MHz, style DVB-T. Using a system clock of 64 MHz everything works perfectly. Now I should be able to decrease the band OFDM to 7/6/5 MHz using the same 64 MHz clock. To get the bandwidth of 8 MHz in 2K (1705 active portant), simply clock output data from a IFFT at period of 7/64e6 = 109.375 nS.
In that way or with that technique can reduce the clock out for obtain 7/6/5 MHz of band ? Without necessarily changing the clock 64 MHz ?
Any idea ?
Thanks.
