Switches (113, 114, 115) are introduced at the intput of the memories, in order to load the set of samples provided by the iFFT block when the first symbol is fed to the input of the emitter. This system may also include a receiver (200) that includes a set of memories (202-205) feeding a weighted summation device (206) coupled to a FFT block (201). Switches (213, 214, 215) are introduced at the input of the memories in order to load the set of samples received, corresponding to the first transmitted symbol. A method of transmission with preloading of the memories that is extended to OQAM modulation and MIMO systems is also described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multicarrier digital signal transmission system using filter banks and memory preloading for initialization","description":"A transmission system includes an emitter (100) that includes an iFFT block (101) coupled to a set of memories (102-105) feeding a weighted summation device (106).
