Faster Data Requires Faster Processing
Users want faster data rates from broadband wireless systems, longer battery life and lower costs. Can all of these be achieved?
The latest WiFi standards are defining data speeds of over 100Mbit/s. The UWB standards are already defining 480Mbit/s with more than 1Gbit/s already being planned. Point-to-point links in millimetric bands are offering >1Gbit/s today. How can processing technology enable all requirements to be met?
Cambridge Consultants has a proven track record of developing leading edge wireless systems. Our DSP group has developed a tool-set, based around our APE flexible DSP core, that allows designers to configure an ultra-fast Fast Fourier Transform (FFT) core and then output Verilog source code for implementation in either FPGAs or ASICs.
FFT Core Features:
- Core can perform more than 4 million 128-point FFTs or inverse FFTs per second
- Highly efficient Radix-2 based design for lowest silicon cost
- Real or complex buffered inputs
- Software application to generate optimised Verilog source from user requirements
- Bit accurate C and MATLAB models
- Suitable for FPGAs and ASICs
Additionally, Cambridge Consultants' DSP group has experience of using highly parallel DSP processors to implement software defined radio (SDR) implementations for broadband wireless applications. These devices can offer scalable solutions to enable even the most complex multi-antenna, multi-sector access points or base stations to be implemented as a software-defined radio. These technologies are applicable to OFDM and OFDMA based systems such as WiMAX, WiFi and UWB.
