What is OFDMA ?

  • OFDMA is Spread Spectrum technique based on Spreaded Multi Tone Modulation.
  • OFDMA divided the allocated spectrum to groups of Sub carriers called Sub-Channels.
  • OFDMA Sub-Carriers are pseudo randomly spreaded on the entire spectrum for achieving frequency diversity (could be group of subcarriers or separate subcarriers).
  • OFDMA combines FDMA and TDMA Access scheme, OFDMA divided the BW resources between users, By Assign Multiple Sub-Channels and multiple time slots per user,
slide27

OFDMA-TDMA Principles

Using OFDMA/TDMA, Sub Channels are allocated in the Frequency Domain, and OFDM Symbols allocated in the Time Domain.

slide28

Using Special Permutations for Sub carrier or clusters allocation

  • Carriers/Clusters are allocated by a basic series and it’s cyclic permutations for example:
  • Basic Series:

0,5,2,10,4,20,8,17,16,11,9,22,18,21,13,19,3,15,6,7,12,14,1

  • After two cyclic permutations we get:

2,10,4,20,8,17,16,11,9,22,18,21,13,19,3,15,6,7,12,14,1,0,5
