	The BitRage Enabled® CR45-A 5.8 GHz DS-3 Wireless System BitRage’s proprietary digital signal processor (DSP) technology allows the CR45-A to achieve high levels of performance even under extreme conditions. Specifically, the processor in conjunction with BitRage’s radio technology allows the CR45-A to achieve distances up to 35 miles with 45 Mbps error-free (1x10^-10 or better) full-duplex actual throughput without the extensive overhead and latency of forward error correction (FEC). The BitRage digital signal processor allows the CR45-A to reach into the noise and restore the signal with complete accuracy. The diagram below shows how the processor works in a lab test of the CR45-A system.

Fig. 1, shows a DS-3 signal from an HP/Agilent^TM test generator. Please note that even with a test generator, the signal has tails.

In Fig. 2, the BitRage processor has enhanced, conditioned and encoded the signal and then sent it out over the BitRage RF transceiver. Note that the enhanced DS-3 signal is actually cleaner than the original signal from the test generator.

In Fig. 3, the signal has been received at the end of the link by the other BitRage RF transceiver. Note that the signal quality has degraded and is very noisy.

In Fig. 4, the BitRage processor at the receiving end reaches into the noise, pulls out the original signal and then processes it so that the delivered signal ends up actually better than the original DS-3 signal from the test generator in Fig. 1.
