Low-power wireless receivers and low-power communication methods and systems are provided. According to some embodiments, a low-power wireless receiver can comprise an input module, a controller, and a feedback loop. The input module can receive a wireless signal from a wireless communication channel. The controller can receive the wireless signal and provide a control signal corresponding to the wireless communication channel. The controller can be operatively configured to dynamically modify the control signal responsive to conditions of the wireless signal and/or the communication channel. The feedback loop can be disposed between the controller and the input module and can dynamically provide the control signal to the input module such that the input module can modify quality conditions of the wireless signal. Dynamic adaptations can occur in real-time so that a low-power wireless device can manage power consumption in response to a quality of signal metric that reflects conditions of a wireless communication channel. Other embodiments are also claimed and described.

Methodology for designing environment adaptive ultra low power wireless communication systems and methods

A bit error rate test on a transceiver is accelerated by adding a phase offset to data phase encoding and decoding in the transceiver and by mapping bit error rate test results from an elevated error rate condition to a normal error rate condition for the transceiver. The elevated error rate is accomplished by adjusting the phase of the phase encoder and decoder with the value of the phase offset so that the encoded data transmission signal is not as robust against noise as it normally would be. Noise in the form of an interference signal is introduced during the transmission, and the bit error rate is measured after the receiver has decoded the signal. The bit error rate (BER) data with an elevated propensity for error is mapped against bit error rate data for normal operations. A mapping function is built to map BER(bit error rate elevated) data&#x2014;data from the elevated error rate condition for data encoding, to BER(normal bit error rate) data&#x2014;data from the normal error rate condition for data encoding. The BERdata is mapped to BERdata using the mapping function so that the BER performance of the transceiver may be measured using far fewer test sequences of digital bits.
