摘要

本文提出了两种具有三个时隙的准正交空时分组码(qostbc)，用于两根发射天线。我们还为每个提出的编码推导出相应的解码器。虽然一个解码器促进联合检测，但另一个解码器允许通过额外的预处理进行符号智能检测。一个码比现有的具有三个时隙和两个发射天线的qostbc提供更好的误码率(BER)性能。另一种编码所需的功率更小，性能几乎与现有的qostbc之一相同，具有三个时隙和两个发射天线。

Two new quasi-orthogonal space-time block codes with 3-time slots for LTE-Advanced

In this paper, we propose two new quasi-orthogonal space-time block codes (QOSTBCs) with three time slots for two transmit antennas. We also derive corresponding decoders for each of the proposed codes. While one decoder fecilitates joint detection, other one allows symbol-wise detection with additional pre-processing. One code provides better bit error rate (BER) performance than one of the existing QOSTBCs with three time slots and two transmit antennas. The other code requires lesser power and performs neary same as one of the existing QOSTBCs with three time-slots and two transmit antennas.
