摘要： Methods of detecting a pulse sequence in a received signal are disclosed, each of which entails operating on samples of the received signal. One method entails determining a correlation of samples with a reference sequence, and detecting the pulse sequence based on the correlation. Another method entails selecting a reference sample associated with a pulse, and detecting the pulse sequence by analyzing samples based on one or more lengths of a time hopping interval and the reference sample. Another method entails selecting a reference sample associated with non-restricted time hopping intervals, and detecting the pulse sequence by analyzing samples that are based on substantially one or more lengths of a half pulse interval and the reference sample. Further, disclosed is a method of determining a timing drift by selecting samples, determining a time delay between the selected samples, and determining the timing drift based on the determined time delay and an expected time delay.

摘要： System and method are disclosed for synchronization of a transmitting device and a receiving device that communicate with each other via pulse modulation. The synchronization technique entails the transmitting device sending one or more quasi-periodic pulse sequences to the receiving device. A quasi-periodic pulse sequence is based on a substantially periodic pulse sequence, and may include some non-periodic pulses or not include some periodic pulses. The transmitting device may transmit frames each including a preamble that comprises one or more quasi-periodic pulse sequences, and a data payload that may comprise data. The receiving device receives the signal, generates samples of the signal, and detects the quasi-periodic pulse sequences in the received signal by analyzing samples based on a sample associated with a pulse and the period associated with the substantially periodic pulse sequence. The receiving device is further able to detect frames based on the detection of the sequence, and extract data therefrom.

摘要： Adverse effects associated with collisions in a wireless communication system are mitigated by defining one or more values for receive data. Here, data that is expected to be received during a data transmission may be set to a defined value. In some cases the defined value is a predefined value (e.g., zero or some other value). In some cases the defined value is based on noise and/or signals levels in the system. In some implementations a device may define receive data values for a period of time during which data is expected to be received and during which a transmission occurs. In some aspects a hybrid on-off keying scheme is employed to determine received data values.

摘要： An apparatus for data communication that receives a plurality of pulses from a remote communications device, determines a pulse puncturing rate based on the pulses, and punctures or discards subsequent pulses based on the pulse puncturing rate. During intervals when punctured pulses are expected, the apparatus operates in a lower power consumption mode for the purpose of conserving power. In another aspect, a receiving apparatus determines the pulse puncturing rate based on received pulses, and transmits the pulse puncturing rate information to a transmitting apparatus. In response, the transmitting apparatus sends a subset of the pulses it would have transmitted based on the pulse puncturing rate. Because the receiving apparatus receives fewer pulses (e.g., a subset), the receiving apparatus may operate in a lower power consumption mode for longer periods in order to conserve power. Similarly, because the transmitting apparatus sends fewer pulses, it may also operate in a lower power consumption mode for longer periods.
摘要翻译：一种用于从远程通信设备接收多个脉冲的数据通信装置，基于脉冲确定脉冲打孔速率，并且基于脉冲打孔速率对后续脉冲进行穿刺或丢弃。在期望脉冲脉冲的间隔期间，为了节省功率，该装置以较低的功耗模式工作。在另一方面，接收装置基于接收到的脉冲来确定脉冲打孔速率，并将脉冲打孔速率信息发送到发送装置。作为响应，发送装置基于脉冲打孔速率发送其将发送的脉冲的子集。由于接收装置接收到更少的脉冲（例如，子集），所以接收装置可以在较低的功耗模式下操作更长的时间段，以便节省功率。类似地，由于发送装置发送较少的脉冲，所以它也可以在较低的功耗模式下工作较长时间。
