Patent number: 11774538Abstract: A method for transmitting a bit sequence to be transmitted at a frequency fb. A set of codes is determined in advance, wherein each code is associated with a possible value from a block of Nb bits, and each code includes an ordered set of Ns binary symbols intended to be transmitted at a frequency fs. The method includes splitting the bit sequence into N blocks of Nb bits, the frequency fs and the numbers N and Nb being selected such that Ns×fb=N×Nb×fs, associating a code with each of the N blocks according to the value from the blocks, interleaving the binary symbols of the N codes respectively corresponding to the N blocks of bits to be transmitted, the interleaved binary symbols being transmitted at a frequency fc such that N×fs=fc.Type: GrantFiled: December 18, 2019Date of Patent: October 3, 2023Assignee: UWINLOCInventor: Jan Mennekens

Patent number: 10651889Abstract: A method for the detection of a pulse of a signal received by a receiver device, the received signal corresponding to data emitted with a predetermined period Tc, each piece of data being encoded by a presence or an absence of a pulse. The method includes: temporally offsetting of the received signal according to a predetermined number Ns of delays corresponding to different multiples of Tc, so as to generate Ns delayed signals; correlating, at a time that is a candidate for the detection of a pulse, the received signal with each of the delayed signals, in so as to obtain Ns correlation values associated with the candidate time; calculating a maximum correlation value among the Ns correlation values associated with the candidate time; and detecting a pulse of the received signal according to the maximum correlation value.Type: GrantFiled: December 11, 2017Date of Patent: May 12, 2020Assignee: UWINLOCInventor: Jan Mennekens

Patent number: 7269126Abstract: A method for constructing orthogonal codes of length N for use in a network utilizing quasi-synchronous code division multiple access combined with time division duplexing. The method determines the balanced vectors of length N, being all possible cross-correlation vectors resulting from zero cross-correlation of codes of length N. An arbitrary code of length N is utilized, and a bitwise XOR-ing is performed with all the balanced vectors to produce a set of codes with which the arbitrary code is orthogonal. A bitwise XOR-ing of the original balanced vectors is performed and the code is added to a set of orthogonal codes if the result of the bitwise XOR-ing of the original balanced vectors is balanced. The method is repeated until the set of orthogonal codes is complete.Type: GrantFiled: September 15, 2003Date of Patent: September 11, 2007Assignee: Agilent Technologies, Inc.Inventors: Jan Mennekens, Carl Mertens, Lieven Philips, Jurgen Vandermot, Jan Vanhoof
