Both Space-Time (ST) processing and Orthogonal Frequency Division Multiplexing (OFDM) are becoming increasingly important techniques used in physical layer to support the Quality of Service (QoS) for different applications in wireless networks. However, the employment of such techniques affects the scheme designs at higher layers such as channel allocation algorithms at Media Access Control (MAC) layer. Therefore, a crossing-layer development is required. This paper proposes the subchannel allocation algorithms based on space-time OFDM-CDMA systems, and develop the throughput-performance analysis frameworks to evaluate the proposed algorithms.
