    摘要: Systems and methods applicable, for instance, in wireless communications. For example, a wireless node and/or other computer may act to create a candidate signal list and/or may act to measure strength for one or more candidate list signals. As another example, the wireless node and/or other computer may act to calculate average difference between the strength of the strongest signal of the candidate list and the strength of a currently-received signal. As yet another example, the wireless node and/or other computer may act to perform one or more operations to employ the strongest signal of the candidate list in place of the currently-received signal.

    摘要: The invention is directed to efficient transfer of low bit rate services in a communication system. A synchronization symbol which has known characteristics may be included as a first symbol of digital broadcast frames. The synchronization symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. Low bit rate services are allocated to time slots following the pilot symbol used for synchronization allowing for fast access times with maximum power saving capabilities. A user terminal wakes up just before the synchronization symbol and received the data allocated for the low bit rate services. The user terminal may power off for the remaining time slots which are allocated for higher bit services to conserve power.

    摘要: Aspects of the invention are directed to service and channel discovery in a digital broadcast network. A pilot synchronization symbol, which has known characteristics, is included as a first symbol of digital broadcast frames. The pilot symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. So, the rest of the signal can be decoded without trial and error methods after the pilot symbol (and any additional synchronization symbols) is decoded. Channels containing digital video broadcast services can be efficiently detected using the known part of the signal. If the fixed known part is not found from the examined signal, then the signal will be considered a non-digital-video-broadcast signal or an empty channel, and the receiver can promptly proceed to a next channel/frequency. In this way, detecting non-digital-video-broadcast and empty channels becomes relatively fast.

    摘要: In accordance with at least one embodiment, fixed TDM slot/frame structure and statistical multiplexing are combined. A TDM slot, which is fixed (in size and position) is reserved for a variable bit rate service such that the bit rate of the TDM slot/channel is below the average rate of the service. Such a reserved TDM slot may be referred to as a service specific slot. Since the service specific slot is reserved with a bit rate below the average rate of the service, additional capacity is reserved from a rate matching slot, which may be common for multiple services. In this rate matching slot, the capacity may be shared between services according to any suitable strategy for allotting services to portions of the rate matching slot, including, but not limited to, a statistical multiplexing algorithm.
