摘要： The disclosure discloses a method and a system for switching a working mode for a backward compatible broadband wireless network, in order to solve the technical problem of switching between each working mode when various compatible modes based on different channelized sets exist in the broadband wireless network. In the disclosure, an access point (AP) indicates its current working mode by a system configuration message; the AP instructs a non-AP associated with the AP to switch a working mode by a mode switching message or a frame exchange sequence; and the non-AP switches the working mode according to instruction information included in the mode switching message or the frame exchange sequence after receiving the mode switching message or the frame exchange sequence. Through the scheme of the disclosure, a wireless point can be switched between each working mode when various compatible modes based on different channelized sets exist in the broadband wireless network, thereby setting up a broadband wireless network supporting backward compatibility.

摘要： Transmitters supporting multiple modulation modes and/or multiple frequency bands are described. A transmitter may perform large signal polar modulation, small signal polar modulation, and/or quadrature modulation, which may support different modulation schemes and systems. Circuit blocks may be shared by the different modulation modes to reduce cost and power. For example, a single modulator and a single power amplifier may be used for small signal polar modulation and quadrature modulation. The transmitter may apply pre-distortion to improve performance, to allow a power amplifier to support multiple frequency bands, to allow the power amplifier to operate at higher output power levels, etc. Envelope and phase distortions due to non-linearity of the power amplifier may be characterized for different input levels and different bands and stored at the transmitter. Thereafter, envelope and phase signals may be pre-distorted based on the stored characterizations to compensate for non-linearity of the power amplifier.
