Abstract

A novel single-carrier-based space-time code design to exploit the advantages of frequency-selective channel is proposed in this paper. The new design is based on multiplexing independent streams of space-time codes in a time-interleaved fashion followed by symbol-wise phase rotations. The advantage of such design is that it guarantees full space-time-multipath diversity by using the traditional space-time codes originally designed for flat fading channels as the constituent codes. Another advantage is that this approach incurs no loss in bandwidth-efficiency and it alleviates the problem of high PAPR in OFDM-based space-time code. The design is potentially suitable for any number of transmit antennas or multipaths. The simulations results indicate that full space-time-multipath diversity is attained using this new approach, and comparisons with some existing space-time codes designed for frequency-selective channel are made to show its performance advantage.
