METHOD OF DIFFERENTIAL SPACE-TIME CODING, UWB TRANSMITTER SYSTEM AND UWB RECEIVER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method of differential space-time coding of blocks of 2, 4 or 8 information symbols belonging to a 2-PPM modulation alphabet, for a pulse UWB-MIMO system with 2, 4 or 8 transmitter antennas.;SOLUTION: In the two pulse UWB transmitter systems 540₁, 540₂, having 2, 4, or 8 antennas each, differential space-time coding is performed without introducing an inversion of the polarity of pulses while providing maximum diversity and a unit rate, and furthermore an associated receiver system, not require channel estimation, is provided.;COPYRIGHT: (C)2010,JPO&INPIT
