摘要： A method for computing a gain control metric used in controlling gain in a wireless repeater operates to store correlation and normalization values associated with the gain control metric for the previous N samples in registers. For each new sample of the gain control input signal, the correlation and normalization values are computed by discarding the multiplication terms of the obsolete sample and adding the multiplication terms of the new sample to the stored correlation and normalization values. In this manner, the complexity of the computation is greatly reduced and the complexity of the computation does not increase with the integration length.

摘要： The embodiments utilize OFDM symbols to communicate network IDs. The IDs are encoded into symbols utilizing the network IDs as seeds to scramble respective pilots that are then transmitted by utilizing the symbols. The pilots can be structured into a single OFDM symbol and/or multiple OFDM symbols. The single symbol structure for transmitting the network IDs is independent of the number of network ID bits and minimizes frequency offset and Doppler effects. The multiple symbol structure allows a much coarser timing accuracy to be employed at the expense of transmitting additional symbols. Several embodiments employ a search function to find possible network ID candidates from a transmitted symbol and a selection function to find an optimum candidate from a network ID candidate list.

摘要： Methods and apparatus for decoding frame packet data in a communication system to reduce latency for decoding particular types of broadcast signals in a frame. In particular, decoding of a communication signal includes demodulating at least a particular type of encoded broadcast channel modulation symbol received in a frame before completion of reception of a certain number of frames each including the particular type of encoded broadcast channel modulation symbol are received. After demodulation, the demodulated encoded broadcast channel modulation symbol is then decoded by a decoder. A determination is then made whether decoding of the first broadcast channel modulation symbol is successful. If decoding is successful, decoding of subsequent broadcast channel modulation symbols is terminated. Otherwise, decoding is incrementally or iteratively continued (i.e., a next received frame and so on) until decoding is determined to be successful.

摘要： Methods and apparatus for including mode information in a wireless transmission frame, which is useful for system acquisition. In particular, a first information bit is provided in a preamble of a transmission frame, where the bit is configured to indicate that a wireless communication system is operating according to either a time division duplex (TDD) mode or a frequency division duplex (FDD) mode. The addition of a single bit minimally affects the resources of the preamble. Additionally, another bit resource already present in the preamble for normally communicating whether FDD transmissions are full duplex or half-duplex transmissions, may be further allocated to indicate partitioning information concerning TDD mode transmissions when the first bit indicates TDD mode, thus affording additional information communicated in the frame without increasing preamble resources.

摘要： A multipath signal searcher (204) used in CDMA wireless communication systems is provided. Search paths (214) of the multipath signal searcher are grouped together and assigned by an offset assignment/timing block (210) to search a time offset within a search window. The search paths may be operated In serial or parallel operation mode. In either mode, the search paths are individually assigned to search over one of a group of time offsets that are distributed across the search window evenly. In parallel mode, the search paths are not only grouped to search only a given set of time offsets within the search window, but different groups of search paths are offset to commence searching at different times then other groups of search paths to more quickly update a finger manager and more quickly retrieve the mobile communication signal.
