Multiple-input multiple-output, wireless systems are able to realize high spectral efficiency and high performance communication links. The benefits from using multiple antennas at the transmitter and receiver are associated with some costs. The most essential difficulty for this kind of systems is the increased complexity of recovering the transmitted signal. When the capacity rises linearly, the detection complexity increases exponentially. This paper presents an overview of the signal detection methods known in theory and particularly describes the main design approaches to MIMO systems: spatial multiplexing and transmit diversity. The article shows classes of receivers, which are used in these strategies. The most important algorithms with their assumptions and computational complexity are also discussed. The introduced receivers are briefly characterized and compared.
