摘要:While transmitting the data over communication channel, various problems such as communicationerror and mismatch arises. For reducing those errors, frequency selective I/Q imbalance using Direct Conversiontransmitters can be implemented. I/Q imbalance compensation procedure has been derived and incoherentmeasurements are required for avoiding the need for time, frequency and phase synchronization between the transmitterand the RF measurement unit. By using I/Q imbalance the Bit Error Rate and Throughput value will be improvedbecause of that Efficiency will be low and long data transmission will be occurred. To overcome this I/Q imbalance,signal injection method will be used. In signal injection extra default signal is added in that phase and gain will becompared because of that the mismatch occurred here will be reduced.This architecture presents a good balancebetween different design aspects and enables to minimize the sampling frequency of the Digital-to-Analog (DAC) andAnalog-to-Digital (ADC) Converters.
