A new high rate serially concatenated space-time code

Using high rate recursive systematic convolutional code (RSCC) as the basic element and the trace criteria as the design principle, a new kind of high rate recursive space-time trellis code (HR-RSTTC) is designed for serial concatenation. By making the number of RSCCs and the coding rate of each RSCC be variable, our designed HR-RSTTC can adjust the data rate according to the transmit antenna number and the modulation scheme. It is verified that, in independent fading channels, the minimum diversity gains of the serially concatenated space-time trellis code (SCSTTC) constructed with HR-RSTTC is 2M(M is the number of receive antennas). In comparison with the traditional SCSTTC, the new SCSTTC can achieve the same data rate with lower complexity and no performance degradation. With the same transmit antenna number and modulation scheme, the new SCSTTC have higher data rate than the traditional SCSTTC
