AM band transmission using multi-tone modulation

A communication system for communicating information from a utility distribution network, the communication system comprising:

• a transmitter for transmitting the information, the transmitter comprising:
• a digital signal processor modulating the information into a plurality of carrier frequencies;
• a digital-to-analog converter connected to the digital signal processor for converting the modulated information into an analog signal;
• and
• a wide band radio frequency (RF) modulator connected to the digital-to-analog converter and receiving the analog signal, the wide band RF modulator modulating the analog signal in an AM frequency band wherein the multi-tone modulated analog signal is transmitted in the AM frequency band by the transmitter wherein the transmitted multi-tone modulated analog signal comprises transmitted information;
• a receiver for receiving the transmitted information from the transmitter, the receiver comprising:
• a wide band radio frequency (RF) demodulator for receiving the transmitted information, the wide band RF demodulator demodulating the transmitted information into a received analog signal;
• an analog-to-digital converter connected to the wide band RF demodulator for converting the received analog signal to received digital data;
• and
• a digital signal processor connected to the analog-to-digital converter and receiving the received digital data, the digital signal processor constructing the received digital data and forming received information.
