摘要： A received signal having pilots is converted to a first signal in the frequency domain having the pilots. The pilots are extracted from the first signal to obtain extracted pilots to form a second signal. The second signal is used to provide a first estimate of a channel. The first estimate is converted to the time domain. Noise is removed from the first estimate in the time domain to provide a second estimate of the channel in the time domain. An autocorrelation of the channel in the frequency domain is determined using the second estimate of the channel. Extension signals are determined using the autocorrelation. The extension signals are appended to the first estimate of the channel to obtain a third estimate of the channel. The third estimate is used to provide a data signal in the frequency domain.

摘要： Various methods of allocating uplink control channels in a communication system are implemented at a resource scheduler or a user equipment (UE). In one method the scheduler reserves resources for a downlink data channel and signals a corresponding downlink data channel grant and also reserves resources for a persistent uplink control channel for a longer duration than the data channel grant. Signaling overhead associated with a grant for this persistent uplink control channel is reduced over a full dynamic grant. A predetermined rule can be used at the scheduler and at the UE to avoid overhead signaling associated with a grant for this persistent control channel. Predetermined rules at the UE and scheduler can also be used to reserve appropriate resources and select appropriate MCS levels for control information and the control information and uplink data can be transported over a common uplink channel when a time overlap occurs between an uplink data channel and the persistent control channel.
摘要翻译：在资源调度器或用户设备（UE）中实现在通信系统中分配上行链路控制信道的各种方法。在一种方法中，调度器为下行链路数据信道预留资源，并向相应的下行链路数据信道授权发送信号，并为持续上行链路控制信道预留比数据信道授权更长的持续时间的资源。与该持久上行链路控制信道的授权相关联的信令开销通过完全动态授权而减少。可以在调度器和UE处使用预定规则来避免与该持久控制信道的授权相关联的开销信令。 UE和调度器上的预定规则也可以用于保留适当的资源，并为控制信息选择适当的MCS级别，并且当在上行链路数据信道与上行链路数据信道之间发生时间重叠时，控制信息和上行链路数据可以通过公共上行链路信道传输持续控制通道。

摘要： A method and apparatus samples (902) a currently received symbol to form sampled values corresponding to sampling times, and evaluates (904) the currently received symbol to determine (906) its value. The method and apparatus recalls (908) a last previously received symbol and selects (916), from a plurality of thresholds (302), a threshold based upon the currently received symbol and the last previously received symbol. The threshold is known to be crossed consistently midway in time between the centers of two adjacent nominal symbols determined by the currently received symbol and the last previously received symbol. The sampled values are compared (920) to locate two adjacent samples, one having a first sampled value greater than the threshold and one having a second sampled value less than or equal to the threshold. A timing phase error is then computed (922, 924) from the first and second sampled values.

摘要： In accordance with at least one embodiment, a processor system is disclosed having a SIMD processor device that has a plurality of subsidiary processing elements that are controlled to process multiple data concurrently. In accordance with at least one embodiment, the SIMD processor is a vector processor (VPU) having a plurality of vector Arithmetic Units (AUs) as subsidiary processing elements, and the VPU executes an instruction to transfer table information from a global memory of the VPU to a plurality of local memories accessible by each AU. The VPU also executes an instruction that results in each processing element performing a table lookup from a table stored at its local memory. In response to the instruction, this table lookup uses a portion of a lookup value to access information from the table, and uses another portion of the lookup information to calculate an interpolated resultant based upon the accessed information.
