DIGITAL MULTI-CHANNEL SIGNAL TRANSMISSION SYSTEM USING FILTER BENCHES AND MEMORY PRELOADING FOR INITIALIZATION

摘要

A transmission system includes a transmitter (100) that includes an iFFT block (101) coupled to a set of memories (102-105) that power a weighted summation device (106). Switches are introduced at the memory inputs, to load the set of samples generated by the iFFT when the first symbol is applied to the input of the transmitter. The system may also include a receiver (200) that includes a set of memories (202-205) that feed a weighted summation device (206) coupled to an FFT block (201). Switches are input to the memories inputs to load the first set of received samples corresponding to the first transmitted symbol. The invention also relates to a memory preloaded transmission method which is extended to OQAM modulation and MIMO systems.
