File Information
Description

One of the file is a guide to see where the other file should be.

  The other file return a 60x15 matrix (60 subchannels x 15 OFDMA Symbols) and it is said on that matrix which user has to transmit in each slot. Then we'll have to allocate the information to send it.

  I know it is a very basic file but it might help someone if he wants to improve that file. I hope so.

  I only simulate the Downlink!

i want BER v.s. No of users (capacity) of MC-CDMA and for OFDMA.
2)BER v.s. distance from BS d(m) of MC-CDMA and for OFDMA.
3)BER v.s. Eb/No (dB) of MC-CDMA and for OFDMA.
4)PDF v.s. CIR (dB) of MC-CDMA and for OFDMA.

Thanks

I have run the program and it was helpful.
I want to plot:
1)BER v.s. No of users (capacity) of MC-CDMA and for OFDMA.
2)BER v.s. distance from BS d(m) of MC-CDMA and for OFDMA.
3)BER v.s. Eb/No (dB) of MC-CDMA and for OFDMA.
4)PDF v.s. CIR (dB) of MC-CDMA and for OFDMA.

Thanks
