Hi, i have a problem with calculating the bit error probability of bpsk modulation using the matched filter:
As it's known well the bit error probability of bpsk (with matched filter at the receiver) can be written as:
P(e) = ?*erfc(√SNR)
My problem is that from an article i've read that if the matched filter output is reduced by a f

this may sound like a stupid question. when i was in college, i was taught that when designing a FET amplifier, i should keep the FET in the linear region.
however, i was told now, whenever i design an CMOS analog circuit, i should keep the transistor in saturation region.
so, what is going on?

The second harmonic of a bpsk signal is free of the phase modulation. so what you have to do is to pass the bpsk signal through a moderate nonlinear active device and to set up a bandpass filter to the second harmonic at the output of this nonlinear network.
The signal after suitable amplification should be divide back (...)

Implementing Digital bpsk modulator is simple. Just use 2 input EXOR gate. Feed the digital modulating signal to one input and at the other input feed the digital carrier, the frequency of which is always integral multiple of modulating signal. The output of EXOR is the bpsk modulated signal. Modulating signal's clock and digital carrier should hav

Every port is -10 dB matched and the mutual coupling is at -25 dB. (BW=200 MHz).
It´s a scanning array (from -45 to +45 degrees).
In my opinion the Scan blindness is a real problem.

In the diagram,the combination of main-amplifier and filter is called linear channel.But main-amplifier may be limit-amplifier,and the filter can be nonlinear,too.So,it seems it is of no sense.
