Abstract
Under realistic mobile radio link conditions involving ground operation with multipath, or with an extended range, OFDM modulation efficiency quickly decreases. In this SBIR program, GIRD Systems will develop methods by which the communication range of links in OFDM-based mesh networks can be extended. Communication at greater ranges with a fixed transmit power means communication at lower SNRs. In order to reliably detect the transmitted information at a low SNR, a new OFDM waveform will be designed that allows advanced signal processing techniques to be incorporated into the receiver in order to allow data recovery of weak signals in noise.
