A method of providing a power supply of an amplifier of a wireless transmission system comprising:
- determining a power at an antenna when transmitting a signal to be transmitted by the amplifier;
- determining a frequency allocation of the signal to be transmitted;
- determining a transmit channel characteristic;
- determining a modulation scheme for transmitting the signal;
- and
- adjusting a parameter of the power supply of the amplifier based on the determining steps to maintain amplifier linearity;
- wherein the transmit channel characteristic comprises the transmit channel bandwidth and wherein determining the frequency allocation of the signal to be transmitted comprises determining the position of the signal in relation to the center point of the bandwidth of the transmit channel.
A processor and associated memory comprising instructions which when executed, cause the processor to
- determine a power at an antenna when transmitting a signal to be transmitted by an amplifier of a wireless transmission system;
- determine a frequency allocation of the signal to be transmitted;
- determine a transmit channel characteristic;
- determine a modulation scheme for transmitting the signal;
- and
- adjust a parameter of a power supply of the amplifier based on the determining steps to maintain amplifier linearity;
- wherein the transmit channel characteristic comprises the transmit channel bandwidth and wherein to determine the frequency allocation of the signal to be transmitted comprises to determine the position of the signal in relation to the center point of the bandwidth of the transmit channel.
A non-transitory computer readable medium comprising instructions which when executed by a processor, cause the processor to
- determine a power at an antenna when transmitting a signal to be transmitted by an amplifier of a wireless transmission system;
- determine a frequency allocation of the signal to be transmitted;
- determine a transmit channel characteristic;
- determine a modulation scheme for transmitting the signal;
- and
- adjust a parameter of a power supply of the amplifier based on the determining steps to maintain amplifier linearity;
- wherein the transmit channel characteristic comprises the transmit channel bandwidth and wherein to determine the frequency allocation of the signal to be transmitted comprises to determine the position of the signal in relation to the center point of the bandwidth of the transmit channel.
