Fully-programmable FPGA-based software-defined radios for military comms

October 08, 2014 // By Graham Prophet
Military communications designs are assisted by technology enabling programming for any combination of waveform and RF transmissions, including MIMO. Altera and Lime Microsystems, a provider of fully programmable RF transceivers, are together demonstrating a multi-standard software-defined radio (SDR) platform.

The SDR platform, based on Lime's field-programmable radio frequency (FP-RF) chip and Altera FPGAs and Enpirion PowerSoCs, can be used to design a radio that can receive and transmit widely different radio protocols (or waveforms) entirely defined by software. This flexible solution, which includes Lime's RF device, the LMS7002M, gives communications systems designers flexibility and performance while consuming a minimum of power.

CEO of Lime Ebrahim Bushehri, comments, “Altera's FPGAs paired with Lime's FP-RF transceivers enable designers to create low-cost, fully programmable wireless systems across multiple applications such as remote radio heads, base stations, military communications, software-defined radios, and Internet of Things (IoT) applications.

Altera and Lime worked closely together to improve the system designer experience. These devices can be easily programmed to produce any combination of waveform and RF transmission, and fully support multiple-input multiple-output (MIMO) wireless applications and other RF techniques useful for military communications.

Altera adds that the cooperation will give developers easy access to open-source, optimised reference designs, boards and software stacks and drivers, to provide an affordable method to build next-generation secure wireless systems.
