We propose a family of orthogonal full rate differentialspace-time block codes (STBC) for three and four transmit antennas. Non-square transmission matrix and multiple amplitude modulation can be used in this family of differential STBCs. The performance of this family of differential STBCs is studied using the Monte Carlo simulation. The results suggest that this family of orthogonal full rate differential STBC achieve full diversity and no channel state information is required.

For four (or more) transmitters, a new design of differentialspace-time block code allowing symbol-wise decoding is presented in this letter. The new design not only has the minimum (symbol-wise) decoding complexity as that by Yuen, Guan and Tjhung (YGT) but also yields a lower error rate. While the YGT code uses a specially designed symbol constellation, the new code uses a conventional QAM with a rotation. At a high data rate such as 3bps/Hz, the new design with symbol-wise decoding complexity can even yield a lower error rate than the code by Zhu and Jafarkhani that has the pair-wise decoding complexity.

In order to improve the transmission rate, a rate-embedded differential space-time code is proposed by embedding the full diversity full rate codes into the traditional differential space-time codes. Theoretic analysis shows that the proposed theme has many advantages, such as high coding gain and low bit error probability. Moreover, the simulation results testify that the new coding scheme can achieve desirable performance, as compared with the traditional differentialspacetime coding schemes (unitary differentialspacetimecode, differentialspacetime block code), especially when transmission rate is high and more receiving antennas are employed.
