METHOD OF SPACE TIME CODING WITH LOW PAPR FOR MULTIPLE ANTENNA COMMUNICATION SYSTEM OF THE UWB PULSE TYPE

摘要

The present invention includes a plurality of radioactive elements (430 ₁ , 430 ₂ , .., 430 _P ) of ultra-wideband including (UWB) as a space-time coding method for a transmission system, the method comprising: M-PPM-M''-PAM modulation alphabet which are information symbols belonging to S = ( ₁ , ₂ , ..., _P ) blocks from the elements of the matrix below and coding a sequence of the obtained vector, Here, the column of the matrix corresponds to the use of the transmission channel, a row of the matrix corresponds to the radiation element, C is the matrix columns or rows, or are defined in the permutation of the rows and columns within, is a M-PPM alphabet permutation () and the modulation of the modulation position of the positions (m ) is defined as a combination of the symmetric operation () of the M''-PAM modulation alphabet for one.
