All electronic devices are susceptible to computational errors due to radiation effects. As electronics get smaller, they are more vulnerable to computational errors due to radiation effects. In mission-critical environments such as military, finance and healthcare, these computational errors are not tolerable. The best solution...

Free-space optical (FSO) communications
Abstract
USC researchers present a system to minimize turbulence interference in FSO communications. The method utilizes a frequency-offset Gaussian pilot tone transmitted along with the data signal, so that both undergo comparable turbulence and modal power coupling. Using a photodetector that optoelectronically...

Telecommunications
Abstract
To enhance communication system capacity, USC researchers have successfully utilized multiplexing of multiple co-propagating beams, with each having a mutually orthogonal spatial modal structure. When multiplexing two polarizations, M frequencies, and N spatial modes, data capacity can be increased by a factor of 2 x M...

Modern radiofrequency (RF) communication systems have high spectral efficiency modulations, which lead to large peak to average power ratios (PAPRs). To prevent excessive amplification of these peaks and other nonlinearities, power amplifiers (PAs) need to “back off” from operating at maximum linear power, and instead...
