From Theory to Practice: MIMO Real-Time Experiments of Adaptive Bit-loading with linear and non-linear Transmission and Detection Schemes
Document Actions
In this paper we investigate the achievable practical throughput with channel aware bit-loading in experiments on a realtime MIMO test-bed. We compare three prominent MIMO transmission schemes, two of them are using only receive side detection namely linear MMSE or MMSE with successive interference cancellation while the third scheme is SVD-MIMO transmission or Eigensspace-signalling, where the transmitter and the receiver both perform a joint signal processing. We show in measurements that a more complex scheme like V-BLAST can increase the link reliability significantly by either increasing the throughput at a fixed bit error rate or improving the bit error rate at a fixed rate. Furthermore we show that Eigenspace-signalling outperforms LMMSE and V-BLAST in terms of achievable throughput especially in the low SNR region but requires accurate channel state information and signal processing at each side of the link.
