Circuit symbol timing algorithm
Sorry I am new to FPGA symbol timing recovery. Let's say I have a perfect channel (small AWGN noise is the only problem). The modulation format is BPSK, and the pulse shaping is square/rectangular ...

Building a DSSS reciever in GnuRadio
I have some questions regarding building a DSSS receiver in GnuRadio. Specifically with the correlation part. I'm having issues with correlating the m-sequence with the received signal. I have been ...

Deriving the BER equations for BPSK; justification for noise variance of $\frac{N_0}{2}$
We model White Gaussian noise (having power $\sigma^2$) as a Gaussian process $n$, whereby for every interval $(t_0,~ t_0 + L)$ the integral $\int_{t_0}^{t_0 + L}n~dt$ is a Gaussian random variable ...

"Best" energy efficiency via capacity of uncoded BPSK AWGN
I have numerically approximated the capacity of an uncoded, binary uniform input, real AWGN BPSK channel versus the SNR using mutual information and entropy, via Gauss-hermite quadrature. My task is ...

BPSK decoding with a non-ideal transmission medium
I'm simulating tranmission via power line communications (PLC) using BPSK. Due to the coupling circuit and slightly inductive nature of the line, the BPSK signal received is far from ideal. In the ...

In wireless communication, is pulse shaping applied to each BPSK signal before OFDM is used, or not?
I have read a number of posts that seem to ask this question but have not been able to find a definitive answer. Here goes... I understand that BPSK with NO pulse shaping would produce a signal in ...
