摘要
The invention relates to a transmission system comprising a sender (100) which comprises an iFFT block (101) coupled to a set of memories (102-105) which feed a weighted summation device (106). Switches are introduced at the inputs of the memories, for loading all the samples generated by the iFFT block when the first symbol is applied to the input of the sender. This system can also comprise a receiver (200) which comprises a set of memories (202-205) which feed a weighted summation device (206) coupled to an FFT block (201). Switches are introduced at the inputs of the memories for loading the first set of samples received corresponding to the first symbol transmitted. The invention also relates to a method of transmission with preloading of the memories which is extended to OQAM modulation and to MIMO systems.
