摘要： Disclosed are methods and systems for tailoring the transmit power of a wireless device to the parameters of the device such as the process split, voltage, and temperature. The device may identify one or more parameters of the device such as identifying the process split, or sensing the operating voltage or temperature. The device may determine an updated transmit power based on the known parameter values identified and any unknown parameter values. The updated transmit power is determined to be a maximum transmit power that meets one or more target transmit metrics, such as EVM and spectral mask, when the device transmits based on the known parameter values and across a range of variations of the unknown parameter values. The device may adjust its transmit power based on the updated transmit power periodically.

摘要： Systems, methods, and devices shape waveforms associated with transmission of data from wireless communications devices. Methods may include identifying, using a processing device, a plurality of portions of a Bluetooth packet for transmission from a wireless communications device, the plurality of portions comprising a first portion and a second portion. Methods may also include determining, using the processing device, a first transmit power associated with the first portion and a second transmit power associated with the second portion, the determining being based, at least in part, on whether the first portion or second portion is used in packet detection. Methods may further include transmitting the first portion of the Bluetooth packet using the first transmit power, and transmitting the second portion of the Bluetooth packet using the second transmit power.

摘要： A wireless communication device and method for operating the same for mitigating interference in a wireless communication network are provided. Generally, the method includes sensing with the wireless communication device pulses of electromagnetic radiation recurring within a band of frequencies used by the device for communication of signals, identifying the pulses as interference, and determining a number of frequencies of the interference within the band of frequencies used by the wireless communication device. Next, a sensitivity of the wireless communication device is reduced upon sensing one of the pulses and repeated at a frequency corresponding to the frequency of the interference. Thus, a spectrum of electromagnetic radiation around the wireless communication device is perceived by the device as free of interference, enabling it to transmit and/or receive more often. Other embodiments are also disclosed.

摘要： A system and method are provided for extending range of devices in a legacy wireless network. Generally, the method involves providing in a transmitter of the system a frame having a first field including a number of preamble segments and a second field including a number of data segments. The transmitter in the system is then operated to transmit at least one of the preamble segments with at least a first transmit power, and to transmit the segments of the second field at a second transmit power, wherein the first transmit power is greater than the second transmit power. Other embodiments are also described.

摘要： A communication system and method are disclosed for parallel processing of received signals to improve sensitivity of the system. Generally, the method includes demodulating a modulated signal in a first demodulator circuit and a second demodulator circuit in parallel. The first and second demodulated signals are then de-whitened, and a cyclic redundancy code (CRC) check performed on each. If the de-whitened first demodulated signal passes the CRC check a first packet included in the signal is sent to a central processing unit (CPU) for further processing. If the de-whitened second demodulated signal passes the CRC check, and the de-whitened first demodulated signal fails, a second packet included in the de-whitened second demodulated signal is transmitted to the CPU for further processing. In one embodiment, one of demodulator circuits is a GFSK demodulator operated in the phase domain and configured to use maximum likelihood sequence estimation. Other embodiments are also described.

摘要： Embodiments can include a method in which a transmission duration for data frames to a plurality of different receiving devices is determined by a transmitting device. The transmission duration can include at least interframe spacings that separate the data frames from one another. The transmitting device can transmit a control message over a medium to reserve the medium for the transmission duration. The data frames can then be sequentially transmitted by the transmitting device to the plurality of receiving devices during the transmission duration. The transmitting device can operate according to a contention based protocol. Related devices and systems are also disclosed.
