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.
In telecommunications and electronics, baud (/ b ɔː d /; symbol: Bd) is a common unit of measurement of symbol rate, which is one of the components that determine the speed of communication over a data channel. It is the unit for symbol rate or modulation rate in symbols per second or pulses per second.
The chip rate of a code is the number of pulses per second (chips per second) at which the code is transmitted (or received). The chip rate is larger than the symbol rate, meaning that one symbol is represented by multiple chips. The ratio is known as the spreading factor (SF) or processing gain:
The code rate of the octet oriented Reed Solomon block code denoted RS(204,188) is 188/204, meaning that 204 − 188 = 16 redundant octets (or bytes) are added to each block of 188 octets of useful information.
In mathematics, a rate is the quotient of two quantities, often represented as a fraction. [1] If the divisor (or fraction denominator) in the rate is equal to one expressed as a single unit, and if it is assumed that this quantity can be changed systematically (i.e., is an independent variable), then the dividend (the fraction numerator) of the rate expresses the corresponding rate of change ...
With a fixed-rate product, such as a personal loan or savings account, the interest rate you sign up for is the interest rate you’ll either pay or earn for the life of the product.
QAM is a parallel form of modulation that transmits two independent signals at a symbol rate that is near, but less than, the bandwidth of 6 MHz. VSB modulation, on the other hand, is a serial form of modulation that transmits one independent signal at a symbol rate that is near, but less than, twice the bandwidth of 6 MHz.
However, if rates fall to 6% while you have a rate lock for 6.5%, you might feel like you missed out. That’s why some lenders offer a float-down option. What is a float-down option — and is it ...
