摘要：

Multiuser detection assisted, multiple transmit antenna based OFDM arrangements are studied in the context of HIPERLAN 2-like systems. It is demonstrated that the system's user capacity can be improved with the aid of unique spatial user signatures, hence supporting a multiplicity of users. The Maximum Likelihood Sequence Estimation (MLSE) detection algorithm outperformed the Minimum Mean Square Error (MMSE) scheme by about 5dB in terms of the required Signal-to-Noise Ration (SNR) and this performance gain manifested itself also in terms of the system's improved video performance.
