### what factor (in dB) is the output SNR or signal power affected by this phase error?

In a BPSK system, if at the receiver the oscillator has a phase error of phi =40° i.e. you are multiplying the received signal with an appropriate cosine signal phase shifted by 40°. Then, after low ...

### Probability of error of 2 identical BPSK channels

we know probability of error of single BPSK system is $Q(\sqrt{\frac{2E}{N}})$ then what will be the probability of error when two independent identical channels are connected and hence what will ...

### Simulation of BPSK in fading channels

I'm trying to simulate BPSK in a channel with Rayleigh fading and AWGN, then obtain the Bit Error Probability (BEP). My program is written in C. I compared my BEP vs $\frac{E_b}{N_0}$ (SNR per bit) ...

### BPSK modulator with DDS on FPGA

I was developing a BPSK modulator with an AD9852. Since AD doesn't seem to offer any way to functionally simulate their DDS ICs, suddenly i see myself in the need to change for a FPGA architecture. I ...
