This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for receiving, by a first wireless device, symbols modulated using a first modulation scheme from a second wireless device, demodulating the symbols to obtain demodulated bits, determining a signal quality associated with the first modulation scheme based on a number of the demodulated bits, determining a value indicative of an expected bit error rate associated with a second modulation scheme based on the determined signal quality associated with the first modulation scheme, determining whether to switch to the second modulation scheme based on the determined value, and transmitting a message to the second wireless device to initiate a protocol exchange with the second wireless device to switch the modulation scheme to the second modulation scheme based on the determination.

Modulation selection based on demodulation data

Certain aspects of the present disclosure generally relate to apparatus and techniques for wireless communication. One example apparatus generally includes an antenna terminal, an amplifier, a matching network coupled between the antenna terminal and an output of the amplifier, a first voltage envelope detector coupled to a node between the antenna and the matching network, and a current detection circuit coupled to the amplifier.
