摘要：

In this letter, we present the extension of the trellis space-time code (STC) concept to include signal mapping drawn from an N-dimensional sphere. The signal points were designed as such to Increase the minimum squared distance between points in the constellation without increasing the average transmit energy. The mapping of the N-dimensional spherical constellations was performed in accordance to set partitioning rules for STC developed by AT&T but optimized for these codes. Performance evaluation For these spherical space-time codes (SSTC) are illustrated in an OFDM framework, which is a natural choice for multidimensional signaling.
