Theoretical bit error rate
WebbThe BER is calculated by comparing the transmitted sequence of bits to the received bits and counting the number of errors. The ratio of how many bits received in error over the … WebbAssume that a hash function selects each array position with equal probability. If m is the number of bits in the array, the probability that a certain bit is not set to 1 by a certain hash function during the insertion of an element is . If k is the number of hash functions and each has no significant correlation between each other, then the probability that the bit is …

Webb23 juli 2024 · Here, M denotes the modulation order and it defines the number of constellation points in the reference constellation. The value of M depends on the parameter k – the number of bits we wish to squeeze in a single M-PSK symbol. For example if we wish to squeeze in 3 bits (k=3) in one transmit symbol, then M = 2 k = 2 3 … WebbTheoretical BER Curves for Common Modulations For large EbNo the following asymptotic performance relationships apply. PCM/FM MSLD ~ 1.1dB better than B/Q/OQPSK. PCM/FM MSLD ~ 3.3dB better than PCM/FM F&S. SOQPSK MSLD ~ 2.5dB better that SOQPSK I&D. PCM/FM MSLD ~ 2.0dB better than SOQPSK MSLD.
