The Relation of Channel Estimation Error Parameters and System Capacity in MIMO CDMA System

摘要：

Pilot length and interval, velocity, the number of transmitting and receiving (TR) antenna numbers are the main parameters of the interpolation channel estimation error in MIMO CDMA system. Above parameters also influence on the MIMO CDMA system capacity. It analyses the relation of above parameters and the channel estimation error with system capacity. When the other parameters are fixed, simulation results show that optimal pilot interval decreases as the velocity increasing; with a fixed velocity, the system performance improves as the TR antenna numbers increasing; with low velocity, the optimal pilot interval increases with the number of TR antennas increasing; it decreases with high velocity. When the channel estimation error is smaller than one percent, the system capacity is increasing with the TR antenna numbers. When it is larger than ten percent, it does not increase nearly.
