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： 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.
