Latest Patents

Carlson holds a patent for a high-speed dial-up telephone circuit that enables full duplex data transmission. This invention describes a 4800 bit-per-second full duplex modem that utilizes the full bandwidth of standard dial-up telephone circuits for simultaneous data transmission in both directions. The design cleverly overlaps two pass-bands in the middle of the telephone band, maximizing bandwidth usage for high-speed data transfer. The overlap is carefully calculated to minimize error rates caused by remote echoes of transmitted data. Additionally, local echoes, which are stronger, are effectively canceled using an echo-canceling technique that operates at the baud rate.
