The DSP802.11S is a complete SDR development/demonstration system comprising a low-cost development hardware, software and firmware.  FC802.11 is the firmware component of the solution for implementing 802.11 /a/b/g. The software configurable core is a fully operational implementation of the 802.11 a/b/g (OFDM) basic functionalities including MAC capabilities. The core and software are designed to target GPP/FPGA architectures including Xilinx Zynq FPGA with embedded ARM processor. The core is very flexible and designed to be adapted within existing advanced Software Digital Radio (SDR) frameworks and application platforms. DSP802.11S is also supported by Sundance DSP SDR400 RF FMC and suitable FPGA boards. Advanced design flows and testing approaches such as HSL (High-Level Synthesis) and Matlab /Simulink are supported.

Different modules of the DSP802.11 form an OFDM PHY (physical interface) which conforms to standard 802.11 specifications. Since being fully configurable, it may be used to implement custom OFDM-based solutions. MAC layer is also available.

Scrambling, Coding, Interleaving and Mapping is done in the GPP (programmed in C language).

AGC, FFT/DFT and Autocorrelation real-time and data intensive operations are performed within the FPGA (or alternatively in GPP).
