摘要

最近，人们提出了一种性能最好的空时格码。这些代码是可达平衡的，因为它们以相同的概率使用星座的点。在此通信中，我们提出了一种比现有方法更简单的新方法来设计QPSK调制和多个发射天线的该类。此外，还提出了针对3和4发射天线的新的更好的平衡码。

An improved method to design QPSK Balanced Space-Time Trellis Codes

Recently, a new class of space-time trellis codes was proposed as having the best performance. These codes are dasiabalancedpsila because they use the points of the constellation with the same probability. In this correspondence, we propose a new and simpler method than existing method to design these class for QPSK modulation and several transmit antennas. New and better balanced codes for 3 and 4 transmit antennas are also proposed.
