Abstract
Bipolar Gaussian pulses are utilized to modulate digital data to communicate information via standard power lines. The pulses are sent in a pulse train, at set intervals. Modulation is accomplished without use of a sinusoidal wave as a carrier. Data is transmitted via power lines while reducing the amount of radiated emissions, enhancing data security, and mitigating interference from other sources. Channel capacity is also maximized by channelization in code space.
