I/Q imbalance correction - Allows you to enable or disable the I/Q Imbalance Correction subsystem. The default setting is Disabled.Дoppler correction - Allows you to enable or disable the Doppler Correction subsystem. The default setting is Disabled.ДC offset correction - Allows you to enable or disable the DC Blocking subsystem. This offset also causes a DC spike in the received signal spectrum.Дigital predistortion - Allows you to enable or disable the Digital Predistortion subsystem. This offset causes errors on the link even when not combined with thermal noise or another RF impairment. Quadrature DC offset (5e-8) - Adds a DC offset of 5e-8 to the quadrature signal amplitude. This offset changes the received signal constellation diagram, but does not cause errors on the link unless combined with thermal noise or other RF impairments. In-phase DC offset (1e-8) - Adds a DC offset of 1e-8 to the in-phase signal amplitude. Phase imbalance (20 deg) - Rotates the in-phase signal by 10 degrees and the quadrature signal by -10 degrees. The choices areДЄmplitude imbalance (3 dB) - Applies a 1.5 dB gain to the in-phase signal and a -1.5 dB gain to the quadrature signal. The selection updates the Phase/Frequency Offset (Doppler Error) block. This causes severe AM-to-AM and AM-to-PM conversion, and is not correctable with digital predistortion.Дoppler error - Allows you to select one of two values of Doppler. This causes moderate AM-to-AM and AM-to-PM conversion, which is correctable with digital predistortion.ДЎ dB (severe nonlinearity) - Sets the average input power to 1 decibel below the input power that causes amplifier saturation. AM-to-PM conversion is a measure of how the phase nonlinearity varies with signal magnitude.Д§ dB (moderate nonlinearity) - Sets the average input power to 7 decibels below the input power that causes amplifier saturation. AM-to-AM conversion is an indication of how the amplitude nonlinearity varies with the signal magnitude. This causes negligible AM-to-AM and AM-to-PM conversion. The choices areДЈ0 dB (negligible nonlinearity) - Sets the average input power to 30 decibels below the input power that causes amplifier saturation (that is, the point at which the gain curve becomes flat). The selected noise temperature changes the Noise Temperature of the Receiver Thermal Noise block. Noise temperature (K) - Allows you to select from four effective receiver system noise temperatures. The second element represents the receive antenna diameter and is used to calculate the gain in the Rx Dish Antenna Gain block. Transmit and receive antenna diameters (m) - The first element in the vector represents the transmit antenna diameter and is used to calculate the gain in the Tx Dish Antenna Gain block.

Changing this parameter updates the Free Space Path Loss block. The default setting is 35600.ДЇrequency (MHz) - Carrier frequency of the link. Satellite altitude (km) - Distance between the satellite and the ground station.

To make changes to the parameters as the model is running, apply them in the dialog, then update the model via ctrl+d. Rectangular QAM Demodulator Baseband - Demaps the data stream from the 16-QAM constellation space.Дouble-click the block labeled Model Parameters to view the parameter settings for the model. I/Q Imbalance Compensator - Estimates and removes I/Q imbalance from the signal by a blind adaptive algorithm.Дoppler Correction - Uses the Carrier Synchronizer block to compensate for the carrier frequency offset due to Doppler. Raised Cosine Receive Filter - Applies a matched filter to the modulated signal using the square root raised cosine pulse shape.ДC Blocker - Compensates for the DC offset in the I/Q Imbalance block.ДЄGC - Sets the signal power to a desired level. LNA (Low Noise Amplifier)- Applies low noise amplifier gain. I/Q Imbalance - Introduces DC offset, amplitude imbalance, or phase imbalance to the signal. Phase Noise - Introduces random phase perturbations that result from 1/f or phase flicker noise. Receiver Thermal Noise (Satellite Receiver System Temp) - Adds white Gaussian noise that represents the effective system temperature of the receiver. Gain (Rx Dish Antenna Gain) - Applies gain of the receiver parabolic dish antenna.
