Latest Patents

One of Dehmas's latest patents is a "Device and method for communications signalling through a fragmented spectrum." This invention pertains to a device designed for the transmission of data across a frequency spectrum that is divided into multiple fragments. Each fragment covers a discontiguous frequency band, and the device includes a packet generator that creates data packets with a constant envelope signaling sequence. This sequence utilizes a modified Zadoff-Chu sequence, which comprises complex symbols associated with each spectrum fragment.

Another significant patent is the "Method for determining multipath components of a UWB impulse channel." This method is crucial for identifying multipath components in a propagation channel, particularly in geolocation systems or impulse radio ultra-wideband (IR-UWB) telecommunications. The method involves emitting a series of UWB impulses at various central frequencies and translating the channel's response into baseband signals. By integrating these signals over time, intensity samples are generated, which are then combined to determine the multipath components exceeding a specific threshold.
