| Summary |
"This paper investigates the performance of a multiple-input multiple-output (MIMO) wireless communication system, when the transmitter is located on a spinning vehicle. In particular, a 2x2 MIMO system is used, with Alamouti coding at the transmitter. Both Rayleigh and Rician statistical models are considered in this paper and are combined with a deterministic spinning model to simulate the channel. The spinning of the transmitting vehicle, relative to the stationary receive antennas causes additional signal fading, and complicates the decoding and channel estimation. The simulated bit error rate is the primary performance metric used. A 4x2 asymmetric Alamouti coding scheme is proposed to increase the performance of the space-time code in this configuration. The 2x2 Alamouti channel code is shown to perform better than the Maximal Ratio Receiver Combining (MRRC) and single receiver (2x1) system in some circumstances and performs similarly to the MRRC in the broadside case. The unsymmetric 4x2 Alamouti code is shown to improve the performance of the 2x2 Alamouti code in the broadside case"--Abstract, p. iii. |
