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.

  • BER Vs SNR/Eb/No for QPSK demodulator

  • 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.

    BER Vs SNR/Eb/No for QPSK demodulator

    Dear Krishna how can we simulat the angular delay profile. Ok Thanks very much krishna. Dear Krishnan, Could you help me writing the code for this question.

    In a BPSK system the received signal can be written as: y = x + n. (1) where x In BPSK constellation dmin = 2A and γb is defined as Eb/N0 and sometimes it is called. SNR per bit. With this definition we have: γb:= Eb. N0. = A2.

    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.

    Could you please kindly correct me what went wrong. Eduardo Solano: If the simulation curve is happening to the right of the theoretical curve, it typically means that you are adding more noise than what is required.

    I am working on super orthogonal space time turbo codes in OFDM systems and will need this e book. Hence we typically go for filters like raised cosine etc. I need it very much my email: nguyenkimhieuha gmail.
