Wireless modem hardware solutions
Coresonic, a provider of baseband processor technology for multimode wireless modems, has announced complete hardware solutions which will allow semiconductor manufacturers to implement WiMax functionality into their semiconductor devices. The WiMax personality pack, based on the company's LeoCore programmable baseband processor technology, provides complete IEEE802.16 functionality, from the RF interface through to the central processor interface. Coresonic's WiMax personality pack supports the mobile WiMax 802.16e-2005 mobile system profile rev 1.4, which will support other modes such as 802.16d and 802.16j. The pack performs everything from ADC/DAC interface to FEC, including digital front-end signal conditioning, synchronization, MIMO channel estimation/compensation, error correction and chase combing. All blocks provided enable a complete solution from the RF interface to interfacing to a CPU (central processor) to run the MAC layer; the processing intensive elements are implemented in hardware to minimize the load on the MAC CPU.
