can anyone help me in matlab codes for using mac layer in wsn
I am implementing codes for Peak to average power ratio (PAPR) in OFDM system. If anyone of you has already worked in this area, i would be very grateful if you can send me any useful codes. So far I've implemented clipping and phase optimization methods but would appreciate if anyone could help me with other methods like Tone (...)
i designed a pipelined adc,and i simulated it at the frequency of nyquist(about half of sampling frequency);but when i deal with the data(txt in dec) in matlab using fuction cal_snr.m(from maxim), the noise power(Pn) is negetive,why?and snr is complex.i'm really confused.i find when i change the parameter "span",the result is different;but how to g

i am doing the final year project about class D amplfier , use some algorithm to produce PWM , then pass to the power amplifier and low pass filter to generate sound. Since i finish to build the class D amplifier in fypga and also able to see the power spectral of the generated PWM to measure the THD of the board. The only thing i need to do now
this term my subject is simulate a power amplifier with predistortion in matlab, i have designed a model, but it is not good enough, could you help me if you had done the same befor? send me your model or give me some advices, please, or tell me which models you used in your work, how to use them? thank you

how to send transmitted power of a signal along with the signal in matlab......Need help for Example the receivec signal is y =hx+n if x is BPSK transmitted signal h is rayleigh fading channel n is AWGN how can I incorporate the transmitted signal power in this formula?
hi all I'm using the functions(fft,ifft) in a matlab code,theoretically signal power must not be changed before and after transformation according to Parsaval theorem. But when calculating the signal power before and after using E{X^2},the power of the 2 signals aren't the same. please can any body helping solving this (...)
I want my codes to pass through AWGN channel in matlab. matlab have a function, AWGN case1 : y = awgn(x,snr) case2 : y = awgn(x,snr,sigpower) case3 : y = awgn(x,snr,'measured') . . . Accoding to the Description, using case1 power of x must be 0 dBW. why do that? Why (...)

That question is bad! There is no "n" variable. a = 0.88 * exp( j*2*pi/5 ); % This is a Complex number nn = 0:40; % This is an array xn = a.^nn; % "xn" is a Complx # raised to a power "nn" for n = 128. % this looks like it wants to be a loop w/128 i
You need orinoco tool for algorithm power analysis.
do FFT, if signal frequency is fin, then 2*fin, 3*fin .. N*fin inside the frequency band (or inband) are harmonic, sum the total power of harmonic, then you get total harmonic power, / signal power is harmonic distortion in db. Another formula is sqrt(harmonic power)/sqrt(signal power), unit is %.
