With a total of 15 patents to his name, Isaksson has developed innovative solutions that address various challenges in communication systems.
Latest Patents
One of his latest patents is focused on near-echo suppression. This hybrid circuit can be used to substantially reduce near echo signals. The circuit includes a balanced 2-wire to 4-wire hybrid for interconnecting a two-wire receive path and a two-wire transmit path to a two-wire transmission line. The two-wire receive path connects the balanced hybrid to an A/D converter, while the two-wire transmit path connects a D/A converter to the balanced hybrid. The two-wire receive path contains a filter, dimensioned to remove signals transmitted from the D/A converter. This invention is particularly adapted for use with Frequency Division Duplex (FDD) and Orthogonal Frequency Division Duplex (OFDD) systems.
Another significant patent by Isaksson involves multi-carrier transmission systems. This system has a plurality of transceivers, each equipped with a receiver and a transmitter. Data is transmitted between the transceivers by modulating the data onto a multiplicity of carrier waves in the form of multi-bit symbols. Each carrier wave constitutes a channel, and the number of bits per symbol varies between channels and, within a channel, with time. The multi-carrier system is designed to synchronously update the bit loading parameters associated with each channel by transmission of data over a control channel.
