## Eb no snr qpsk waveform

I do not understand why a complex gaussian noise is required. Do you have matlab code for it. Am doing good. So I should be very grateful if you can help me with this. Thank for answer. Then perform hard decision decoding on that signal. I look forward to hear from you soon.

Eb/N0 is an important parameter in digital communication or data transmission. It is a normalized signal-to-noise ratio (SNR) measure, also known as the. number of alternative modulation symbols, e.g. M = 4 for QPSK and M = 8 for 8PSK. Eb * bit rate is the total power of the received signal, and No * bandwidth is the total SNR(dB) = Eb / No (dB) + 10 * logbase10(bit rate / bandwidth) http:// 2/.

Figure 2: The figure shows a QPSK waveform. . Eb/No. 14 5 Optimum Receivers AWGN. Consider M = 2, the SNR is given as. 7.

Setting the state of the rand or randn enables one to do so. Hussein: Thanks. Tony: In excel, make sure that you are selecting log-scale for the y-axis. Or is it LLR gives this inverse sign? THe received symbols should then be converted again to a bit stream. Hi there, very useful site.

TQ so much if you can help me.

To make the noise model same as with other modulation schemes, I kept it as complex. Talib: Replies: 1. The following is confusing.

I got necessary informations about Vitervi Algorithm, Hard and soft decision. Thank you for your effort… i have some question 1. Many Thanks.

Am doing good.
