What does samples per symbol mean?

Samples Per Symbol. Samples per symbol determine the acquisition bandwidth. The bandwidth occupied by the transmitted signal is based on the modulation type, symbol rate, and pulse-shaping filter used. To successfully perform demodulation, the analyzer must acquire the complete bandwidth.

How do you calculate sample per symbol?

The samples per symbol, sps, is usually not explicitly chosen but is determined from the symbol rate of the signal, F, and sample rate, Fs, on a particular platform: sps=FsF.

What is symbol rate sampling?

The symbol rate is measured in baud (Bd) or symbols per second. In the case of a line code, the symbol rate is the pulse rate in pulses per second. Each symbol can represent or convey one or several bits of data. The symbol rate is related to the gross bit rate, expressed in bits per second.

What is symbol rate in QAM?

As the number of symbols increases, more data bits are transmitted per symbol. For example, 64-QAM is a QAM scheme with 64 symbols, and 256-QAM is a scheme with 256 symbols. 256-QAM conveys 8 bits per symbol (as 256 = 2⁸), so achieving twice the data rate of 16-QAM for the same symbol rate.
