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 OFDM?

Symbols per second

OFDM can generate a new symbol (composed of 48 subcarriers) every 4 microseconds. Based on that, it's possible to signal 250,000 symbol transitions every second on each of the subcarriers.

What is sample 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.

What is a symbol in RF?

A symbol is any distinct state of the communication channel. For example, in a binary (two-state) channel, the states could be two voltage levels, two different values of current, or even two different frequencies — i.e., a simple modem. Such a channel can transmit one bit of information at a time.
