Latest Patents
One of Bernard Raaf's latest patents is titled "Zero insertion for ISI free OFDM reception." This invention describes an apparatus that generates a zero-tail signal for transmission in an LTE/LTE-A cell. The apparatus introduces time domain samples with zero or very low power in specific positions of a time symbol tail. This innovation allows for the coexistence of signals sent by user terminals located at different distances from the base station without inter-symbol interference.
Another significant patent is "Adaptive modulation and coding in a SC-FDMA system." This method involves transmitting data over a channel with a predetermined quality estimate. The process includes splitting the input data stream into multiple sub-streams, processing each sub-stream into symbol subsets, and allocating them in frequency resource blocks based on channel quality. This approach optimizes data transmission by adapting the modulation scheme according to the channel conditions.
