Ricean Multipath channel model implementation

I'm trying to implement a multipath ricean channel model. I had found several resources but I'm kind of lost with too much information. What I have from now is the following step: ...

simulating multipath via tap delays in FPGA

I have a Xilinx FPGA running at 200MHz with an ADC and DAC on board. I am taking a 2462MHz sine wave (pretending it is 802.11b chan 11), mixing it down to 40MHz putting it through my FPGA, mixing it ...

Intersymbol Interference — Root raised cosine filter redundant if doing impulse response equalization?

I'm implementing DBPSK (differential binary phase-shift keying) over audio (44.1kHz sample-rate) using software. Eventually I'll use multiple audio frequencies at once, so I'm using FFTs and inverse ...

Question about fading

Could you please help me to answer this question ? We have a Shannon formula for Capacity as \begin{align} C=B\log_2(1+\frac{h*P}{B*N_0}) \end{align} where h is a random variable which denotes the ...

modelling wireless multi-path channel - is channel response sum of delta(t-path_delay) or “delta” should be smoothed somehow?

Consider the wireless channel. It is mult-path - means that signal is sum of sent signals with some delay and fadings. The standard models for "impulse response" for multi-path channel in wireless is: ...

What effect does mutipath have on estimating optimal sampling time using the averaging method described therein

This question takes off from this question regarding syncronization of BPSK signals. For the sake of argument let us assume 10 samples make up 1 bit. One method currently suggested is break up the ...
