| Scalable OFDMA (scalable orthogonal frequency-division multiple access) is a key technology behind mobile WiMAX (mobile worldwide interoperability for microwave access) and is widely regarded as an enabling technology for future broadband wireless protocols including the 3GPP and 3GPP2 long term evolution standards. cos it can tolerate fading... OFDMA modulation is for physical layer. here is phy design with OFDMA... Data is mapped in the frequency domain onto the available carriers. For this data to be conveyed across a radio channel, it is transformed into the time domain using an inverse fast Fourier transform (IFFT) operation. To provide multipath immunity and tolerance for synchronization errors, a cyclic prefix is added to the time domain representation of the data. Multiple modes are supported for the OFDMA modulation, to accommodate variable channel bandwidths. This scalable architecture is achieved by using different FFT/IFFT sizes. the supported channel bandwidths for .16e.. with FFT sizes...as in it is the overview.... let me know if u find it interesting.... | |

| Hi Bro in Wireless Field,
I want to get papers or ebook about WiMax regarding with
1.Mesh Mode Operation 2.Details about Mac frame structure 3.Contention resolution mechanism
I need them.Pls help me and share information.

Kmthu hi kmthu, u must be the one who is on "wireless network protocol" at NUS and asked for wimax mesh MAC assignment right? K ... let me know ur email address.. i have what u need..... with regards, bo bo | |

| Thanks,
Especially on IEEE 802.16.I have IEEE 802.16 2004 ebook sent by Thein Than Tun who is from NTU.I need more books and paper.I have time enough to read and prepare to make a report.
Best rgds, Kmthu | |
