Need to know the basics of OFDM

OFDM (urgent)

Hi..

Can any body tell me from starting (serial to parallel) block till transmitter channel how many input and output of each block

please assume any value of each parameter.

Thanks

from serial to parallel : here the IFFT block will take the data (IFFT block is decided by your application it maybe 64, 128 ...) then the parallel to serial then the GII

I want to make an individual block of OFDM in matlab can you please tell me what is the input and output of each block (please assume any values of parameters fore.g no of subcarrier=128, fft length=128 etc)

No Blocks

1 Serial to Parallel

2 QAM or QPSK Mapper

3 IFFT

4 Insert Cyclic prefix

5 Parallel to Serial

6 Digital to Analog

7 Low Pass Filter

8 Channel (add noise)

9 Analog to Digital Convertor

10 Serial to Parallel

11 Remove Cyclic Prefix

12 FFT

13 Equalization

14 DeMapper QAM or QPSK

15 parallel to serial


Thanks
