Method and transmitting device for encoding data in a differential space-time block code

摘要

A method and a corresponding transmitting device to encode data with a differential space-time block code. A code matrix is calculated recursively from a momentary data matrix with a previous code matrix as a DSTBC block with symbols that are to be transmitted, the data matrix is formed from at least two data symbols that are to be transmitted, and the amplitude is modulated. Amplitude modulation data is encoded into an amplitude difference of at least two data symbols within each individual DSTBC block.
