WebData-rate units. In telecommunications, data-transfer rate is the average number of bits ( bitrate ), characters or symbols ( baudrate ), or data blocks per unit time passing through a communication link in a data-transmission system. Common data rate units are multiples of bits per second (bit/s) and bytes per second (B/s). Web$\begingroup$ did my research, cant use that formula when dealing with an odd number of bits per symbol, for which bits per symbol for 32QAM is 5... $\endgroup$ – John Smith. May 13, 2014 at 19:41 $\begingroup$ @JohnSmith: The problem is that there isn't a standard definition of what 32-QAM is. For non-square QAM modulations, there are ...

WebMar 24, 2015 · The birth of the bit. Thinking of information in terms of bits — 0s and 1s — seems like something that firmly belongs to the modern era, but the idea has been around for over 60 years. It was the … WebMay 22, 2024 · This is the modulation efficiency (also referred to as the channel efficiency, channel spectrum efficiency, and channel spectral efficiency ), (5.5.3) η c = R c / B c. where R c (in bit/s) is the bit rate transmitted on the channel, so η c has the units of bit/s/Hz. The unit is dimensionless, as hertz has the units of s − 1. The bits per symbol is the (modulation's power of 2) × (Forward Error Correction). So for example, in 64-QAM modulation 64 = 2 6 so the bits per symbol is 6. The Forward Error Correction (FEC) is usually expressed as a fraction; i.e., 1/2, 3/4, etc. See more In a digitally modulated signal or a line code, symbol rate, modulation rate or baud rate is the number of symbol changes, waveform changes, or signaling events across the transmission medium per unit of time. … See more In telecommunication, concerning the modulation of a carrier, a significant condition is one of the signal's parameters chosen to represent information. A significant condition could be an electric current (voltage, or power level), an optical power level, a See more • What is the Symbol rate? • "On the origins of serial communications and data encoding".
