Abstract :
The performance of a new detection algorithm for uncoded multiple input-multiple output (MIMO) systems based on the complex version of the sphere decoder (SD) is analyzed in this paper. The algorithm performs a fixed number of operations to detect the signal, independent of the noise level. Simulation results show that it can be applied to high-dimensional MIMO systems presenting a very small bit error ratio (BER) degradation compared to the original SD. In addition, its deterministic nature makes it suitable for hardware implementation
