System performance of time division IQ-channels receiver due to transient process for digital wireless applications

In this paper, we have studied time division IQ channels receiver (TDIQR) architecture for solving IQ mismatch problem of direct conversion receiver. TDIQR having the process of I and Q signals on the same chain of receiver's RF units was an elaborated model. We analyzed the PER performance vs. noise of the wireless local area network (WLAN) system and especially the impact of transient process on the receiver.
