Abstract
Future broadband communication systems should provide low-complexity data processing, higher data rate, and stronger performance. Performance analysis itself is a critical stage in the field of wireless communications due to the nature of multipath fading that are encountered due to scatters. The ultimate performance measures are the bit error rate and average spectral efficiency of the system being studied. In particular, the BER performance depends on the employed detection scheme, signal to-noise ratio (SNR), and diversity order. This paper addresses a channel estimation method based on Kalman filter with STBC codes for Multiple-Input Multiple-Output (MIMO) systems. Simulations have been done in MATLAB for time-varying Rayleigh faded channels for m-QAM. The proposed technique seems to obtain an error performance closer to that of a known channel information case in severely faded channel considerations.
