hi,I wanna design a transmission link in Simulink.The data is Manchester coded.Then goes through Raised Cosine Filter with oversampling ratio 32,data rate 80kbps.Therefore:
1)Ts in Machester coding block is 1/80kHz=12.5*10^(-6),am I right?
2)For the Raised Cosine Filter block, the fc is 80kHz,fs...
Hi,thanks for your response.Erm..I know about the Real-Imaginary to complex and complex to Real-Imaginary block.But how if there is only one input(double) and I need to change it to double(complex) so that It matches with another block which requires a complex input?
I wonder how come after...
The output from "add" block is a real plus imaginary signal,but the Power Amplifier requires complex input and output a complex signal as well.The Bandpass filter requires a real input.Anyone knows the way to change from "double to double(c)" meaning from real to complex signal, and vice...
Hi,I am working with SSB/DSB transmitter simulation in Simulink. These errors occred in memoryless Nonlinearity HPA block in the Merge and Output inside the block.
1)Complex signal mismatch. Output port 1 of 'Memoryless
Nonlinearity/Merge' is a signal of numeric type complex. However, it
is...
simulink rfid
hi,I still having problem when designing the RFID simulation model.It is my first time to do it also.Do you have any simulink transmitter and receiver model that can share with me?Maybe we can share our problem.
how to view a complex signal in simulink
Hi Harmasha, thanks again for your reply.The memoryless nonlinearity is actually the simulink block that i used for high power amplifier and the errors are occured in this HPA block.
I don't know is it correct for me to use this memoryless nonlinearity...
shifting a signal in simulink
Hi Harmasha,thanks a lot for your help.I have tried on putting a 'Abs' block to get y=|u| after the 'Sum' block but still getting the same error-->Complex signal mismatch...
and i stil not very sure on the phase part and how to shift the phase of the output...
local oscillator in simulink
Hi,really thanks a lot for your reply.May i know how to change and where to change the complex value to magnitude and phase value?is it i need to u 'complex to magnitude and angle' block at the output of 'Add' block?But there is only one input for HPA...
Or is it...
Hi,I got some problems here. For SSB, after summation of real I and imaginary Q part using add block,these
error occur in High power amplifier:
1)Complex signal mismatch. Output port 1 of 'Memoryless
Nonlinearity/Merge' is a signal of numeric type complex. However, it
is driving a...
hi,may i know is it i should modulate a manchester coded pulse by using ASK,PSK or FSK before the raised cosine filter?so that i can get a some sort like sinewave output?thanks for any advices.
Raised cosine filter
hi,anyone knows why i couldnt get a continuous sine wave like this:
after i input Manchester coded random data into raised cosine filter but ends up getting square waves in time domain? I am using digital raised cosine filter with filter order=2 and fs =...
