Wimax code blocks Edit

The TileraMulticore, TexasInst , FpGa, PicoChip or FreescaleDsp transmits the data via the following steps.

  • Dataout, Blockencoder, Randomizer, Convolutionencoder, interleaver, modulator, normalize, OFDM, RfTransceiver- Transmitter

The data is extracted by the receiving TileraMulticore at the other end:

  • RfTransceiver-Receiver, OFDM, De-normalize, De-modulator, Deinterleave, Viterbi , Blockdecoder, De-randomizer, Datain

The Tilera seems to be a breakthrough for OFDM as used in Wimax, LTE and 3G. It replaces multiple FPGA cores and is up to 15 times faster that the TexasInst Davinci DSP series but will probably never be available to the public at large. Somebody tell Google to buy out the company. Google is our natural ally in our quest to create unlimited bandwidth.

Wimax RF transceiver Edit

Wimax transceiver is the RF stage chip that transmits the data on a specific frequency. In SA this could be our illegal frequency of 600mhz or 1.3ghz.

* http://www.electronicstalk.com/news/max/max341.html

Additionally, a unique master/slave mode allows two MAX2838 transceivers to operate in MIMO (multiple-input/multiple-output) or MRC (maximal-ratio-combining) configurations for improved system range and data throughput performance. The Maxim MAX2838 operates from a +2.7 to +3.6V supply. It is available in a small, 6mm x 6mm, leadless, 48-pin TQFN package. Pricing starts at US $8.13 (1000-up). An evaluation kit is available to speed designs.

Legend Silicon transceiver Edit

Legend Silicon has introduced the LGS-8G78, a demodulator designed to improve reception of the digital terrestrial television broadcast (DTTB) signals defined by China's GB20600-2006 standard.

FLASH-OFDM Edit

http://en.wikipedia.org/wiki/OFDM Flash-OFDM (Fast Low-latency Access with Seamless Handoff Orthogonal Frequency Division Multiplexing), which is also referred to as F-OFDM, is a system that is based on OFDM and specifies also higher protocol layers. It has been developed and is marketed by Flarion. Flash-OFDM has generated interest as a packet-switched cellular bearer, where it would compete with GSM and 3G networks. As an example, 450 MHz frequency bands previously used by NMT-450 and C-Net C450 (both 1G analogue networks, now mostly decommissioned) in Europe are being licensed to Flash-OFDM operators.

http://www.dataweek.co.za/news.aspx?pklNewsId=29327&pklCategoryID=34

The TCI6484 leverages the same 1 GHz TMS320C64x+ core found in other DSPs from TI, making it code compatible with previous generations. TI also offers optimised software libraries for WiMAX Wave 2, LTE and HSPA+. These libraries enable higher channel density as well as lower power per channel. System level testing can be accomplished with a hardware development card that supports two TCI6484 devices - Supplied By EbvElectrolink
