spreading factor

Number of chips per bit, or chips per symbol, is the spreading factor.

The ratio is known as the spreading factor (SF) or processing gain:

Hyaluronidase also known as spreading factor that breakdown hyaluronic acid and help in spreading of Staphylococcus aureus.

Orthogonal variable spreading factor (OVSF)

Code-division multiple access (CDMA), where different amount of spreading codes or spreading factors can be assigned to different users.

The ratio is called the spreading factor or processing gain and determines to a certain extent the upper limit of the total number of users supported simultaneously by a base station.

The allocation is in units of channelisation codes for Spreading Factor 16, of which 16 exist and up to 15 can be allocated to the HS-DSCH.

The specification is based on Time-division duplex technology with Spread spectrum frequency hopping to minimise the impact of interference and variable spreading factors to increase range and accommodate low power devices.

Weightless uses Time-division duplex operation with frequency hopping and variable spreading factors to increase range and accommodate low power devices in frequency bands, or channels, within the terrestrial television broadcast band.

The CDMA radio configuration is defined as a combination of forward and reverse traffic channel transmission formats that are characterized by physical layer parameters such as data rates, error-correction codes, modulation characteristics, and spreading factors.

OFDMA resembles code division multiple access (CDMA) spread spectrum, where users can achieve different data rates by assigning a different code spreading factor or a different number of spreading codes to each user.

Orthogonal variable spreading factor (OVSF) is an implementation of Code division multiple access (CDMA) where before each signal is transmitted, the signal is spread over a wide spectrum range through the use of a user's code.
