problēma ar skicējot BER un BPSK

[saeddawoud]

Hello,

Es cenšos gabals BER par BPSK, bet tas nedarbojas pareizi, es nezinu kāpēc.Es lietoju šādu kodu:

Kods:

M = 2;

chan = rayleighchan (1 / 10000, 100);

TX = randint (50000,1, M);

txSig = pskmod (tx, M);

y = filtrs (Chan, txSig);SNR = 00:02:20;

n = 1: garums (SNR)

rxSig = awgn (y, SNR );

RX = pskdemod (rxSig, M);

[NErrors, BER ] = biterr (TX, RX);

beigasBERtheory = berfading (SNR, "PSK" M 1);

semilogy (SNR, BER "k-*", SNR, BERtheory, "r");
