Definitions
- Fig. 1 illustrates parts of a known space-time block code (STBC) transmitter
- Fig. 5 illustrates a decoding arrangement for use with the coding arrangement of Fig. 3.
- the symbols produced by the second coder- 32 are de-interleaved by the de- interleaver 36, which operates conversely to the interieaver 34, to produce symbols in each symbol interval which are identified as x2 ⁇ and x2 2 as shown in Fig. 3. It is assumed here for convenience and simplicity that the coders 30 and 32 are identical, but as for known turbo coders this need not necessarily be the case and the coders 30 and 32 could instead differ from one another.
- the selector 38 is controlled by a control signal of alternating ones and zeros (1010... as illustrated) at the bit group rate, and performs selection and puncturing functions as represented in Fig. 3 by switches within the selector 38.
- Table 5 represents, for the feedforward code and the derived recursive feedback code, the next state of the coder and the two output symbols of an 8-state QPSK STTCM coder for a coding arrangement for two transmit antennas :
