Abstract :
The Millimeter Waves are allocated with 60GHz frequency range as an unlicensed band worldwide. Millimeter waves become very useful for short-range communications because of its high data rate, its large-available bandwidth of 7GHz and the Oxygen absorption present at that band. The 60GHz indoor channel contains much of multipath components and needs the use of statistical parameters in modeling the channel. At 60 GHz, the free space loss is higher and thus requires the use of antennas with more pattern directivity along with having small antenna dimensions. Considering these factors, in this paper, Triple Saleh Valenzuela (TSV) model is chosen as a suitable model for millimeter waves. The performance of Spatial Multiplexed system for TSV channel model is simulated by assuming a simple indoor Line of Sight (LOS) environment model. Assuming perfect channel estimation, the Bit Error Rate (BER) performance of the 2x2 system is investigated for Zero Forcing (ZF), Minimum Mean Square Error (MMSE), and Maximum Likelihood (ML) receivers.
