Patent ID: 8457234

Claim:
A radio transmission method for a transmitting apparatus having a plurality of transmission antennas, the method comprising: outputting a plurality of coded symbols, wherein the coded symbols are used for space-time block coding a plurality of pieces of data by frequency domain and space domain; generating a first plurality of signal sequences assigned to the plurality of transmission antennas based on a first signal arrangement pattern using a plurality of first block coded symbols comprising a plurality of coded symbols, wherein: the first block coded symbols are formed by assigning the coded symbol per transmission time per transmission antenna, at least two of the coded symbols in a same transmission time among the first block coded symbols transmit mutually different data, the first signal arrangement pattern is a signal arrangement pattern known to a receiving apparatus and is selected from a plurality of signal arrangement patterns representing arrangements of each of the first block coded symbols, and the plurality of signal arrangement patterns form blocks of space-time block coding by frequency domain and space domain; and radio-transmitting the first plurality of signal sequences from the plurality of transmission antennas per transmission time using a common frequency.
