Fixed WiMAX PHY IP CORE

Overview SeaSolve’s Fixed WiMAX PHY IP core is a synthesizable high performance IP core that

implements IEEE 802.16d-2004 PHY functionality. This low latency baseband transceiver core

is developed in VHDL for Basestations and Subscriber Stations. The core offers Fixed WiMAX

Chipset designers, OEM’s and ODM’s a standard compliant platform to accelerate development

process and reduce time to market.
