摘要： A novel and useful self-calibration based production line testing mechanism utilizing built-in closed loop measurements in the radio to calibrate the output power of an external power amplifier coupled to a SoC radio. The mechanism is applicable during production line testing and calibration which is performed on each SoC and associated external power amplifier after assembly at the target PCB of the final product. The mechanism calibrates the TX output power in three phases based on loopback EVM measurements. In a first phase, the PPA in the radio (SoC) is calibrated and gain versus output power is stored in a gain table in on-chip NVS. In a second phase, the maximum PPA TX power is determined using closed loop EVM measurements. The external PA is calibrated in a third phase and the maximum PA power is determined. During this third phase, the maximum power of the device is calculated, compared to the requirements of the particular standard and a pass/fail determination is thereby made.

摘要： A novel and useful range extension and in-band noise mitigation mechanism that uses conventional CRC error detection codes to correct single and multiple bit errors in packets received over a communications link. The CRC error correction mechanism of the invention is particularly suitable for use with communication protocols with weak error correction capabilities. The mechanism uses the linearity property of the CRC calculation to detect the existence of errors in the received packet. The entire received packet is searched for single bit errors and are corrected in a single cycle. If no single bit errors are found, the mechanism then searches for multiple bit errors. Packet retransmissions are used to detect and mark the location of multiple bit errors. Multiple bit errors are corrected by trying a plurality of hypotheses of single bit error corrections. Each hypotheses pattern is investigated to find matching CRC patterns for correction using the single bit, single cycle CRC error correction method.

摘要： System and method for enabling the coexistence of multiple wireless communications on a single unit. A preferred embodiment comprises receiving a schedule of reserved message transfer times from a coexistence unit of a first wireless network in a mobile unit at a coexistence unit of a second wireless network in the mobile unit, selecting an operating mode for the coexistence unit based on the schedule, and transferring messages on the first wireless network and the second wireless network based on the schedule. The first wireless network is restricted to being able to transfer messages only during scheduled times. The sharing of the schedule of reserved message transfer times can enable the transfer of messages in the second wireless network to occur in between the reserved message transfer times, thereby reducing message collisions that can negatively impact data transfer performance of both wireless networks.

摘要： A novel and useful apparatus for and method of reducing or minimizing the power required to detect WLAN signals. The present invention provides a mechanism of detecting WLAN signals using either a modified receive path or a separate low power receiver co-located with the WLAN radio. A secondary radio (such as a Bluetooth receiver) is used to detect the WLAN signals, rather than the primary WLAN radio, wherein the secondary radio consumes significantly less power than the primary radio. To search for a new packet to receive, the WLAN device de-activates or shuts down most of its RF, MAC and PHY circuitry to a level that permits it to be re-activated (i.e. turned back on) within a certain time. The lower power receiver is then used to detect the WLAN signal. If a WLAN signal is detected, the WLAN radio is notified which causes it to be re-activated within sufficient time to receive the packet header. If the WLAN radio detects a valid WLAN packet, the WLAN radio proceeds to receive the remainder of the packet.

摘要翻译： 一种用于减少或最小化检测WLAN信号所需功率的新颖有用的装置和方法。 本发明提供一种使用修改的接收路径或与WLAN无线电共同定位的单独的低功率接收机来检测WLAN信号的机制。 辅助无线电（例如蓝牙接收机）用于检测WLAN信号，而不是主WLAN无线电，其中辅助无线电消耗的功率远低于主无线电。 为了搜索要接收的新分组，WLAN设备将其大部分RF，MAC和PHY电路去激活或关闭，使其能够在一定时间内被重新激活（即重新开启）。 然后使用较低功率的接收机来检测WLAN信号。 如果检测到WLAN信号，则通知WLAN无线电，导致其在足够的时间内被重新激活以接收分组报头。 如果WLAN无线电装置检测到有效的WLAN分组，则WLAN无线电继续接收分组的剩余部分。

摘要： A novel and useful mechanism for reducing the required backoff and the peak to average power ratio (PAPR) needed for an OFDM transmitter whiles still meeting spectral mask and EVM specifications. The mechanism searches, for each packet to be transmitted, for several possible scrambler and encryption sequences that would yield the best spectral mask and EVM with lowest PAPR. The search can be performed using the existing transmitter and receiver PHY circuit chain to modulate and demodulate the candidate hypotheses. Once the scrambler sequence and/or encryption sequence is selected, the packet is transmitted using the selected scrambler and encryption sequences. In addition, the invention exploits the fact that even for very low backoff margins, a reduced number of candidate hypotheses may be tested while still yielding a high probability of meet the spectral mask and EVM specifications.
