Abstract
Disclosed is a differential space-time block coding apparatus with a high transmission rate in a wireless communication system employing multiple transmit antennas and a method thereof. The differential space-time block coding method includes the steps of, when elements of a transmission matrix Bare transmitted in a predetermined block (a vblock) through a predetermined transmit antenna at a predetermined time, modulating a symbol Sof inputted binary data to a symbol S, creating a matrix Sin a block (a (v+1)block) following the predetermined block by substituting the modulated symbol for the matrix P, and then, in order to perform a differential encoding function, multiplying the matrix Bby the matrix Sso as to calculate a new matrix Bto be transmitted in the (v+1)block.
