25. OFDMA CONCEPT

26. 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,

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

28. 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

29. OFDMA Coverage six sectors PUSC(1/2) Capacity: 0.97 Bit/Sec/Hz per sector, Reuse=1 Half of the Sub-channels loaded, No-soft hand-off , No STC, No FAPC, No MIMO

30. STC 2x2 FUSC
