    摘要: Methods and apparatus for splitting Golay sequences into a plurality of subsets of sequence elements and transmitting the subsets are described. The sequence subsets include an equal number of elements, e.g., symbols, from the split sequence and are transmitted using one group of tones per subset. The tones in each group of tones are uniformly spaced with one symbol being transmitted on each tone. The groups of tones are separated from one another by a frequency spacing which is greater, e.g., many times greater, than the frequency spacing between the tones in each group. Low peak to average power ratios are achieved for the transmitted signals while at the same time allowing for a wide band of frequencies to be used to transmit the split sequence. This leads to greater frequency diversity and facilitates frequency and phase related signal measurements by a device receiving the signal.

    摘要: A flexible package for dispensing fluid or semi-fluid items. The package includes a top proximal portion and a bottom distal portion. A leash is defined within a side edge panel and extends from the proximal portion to the distal portion. A user tears the top proximal portion at a tear notch adjacent the proximal portion and then tears the top portion down along the leash in order to keep the top portion coupled to the package and allowing for removal of the package's contents.

    摘要: In a first mode of dedicated control channel (DCCH) operation, a wireless terminal is allocated more segments than in a second mode. The wireless terminal uses different information bit to modulation symbol mapping in the different modes. On a per DCCH segment basis, the same number of modulation symbols are communicated in either mode but more information bits are conveyed in the second mode. Information bits for a DCCH segment are partitioned into two subsets. The two subsets are used to generate another set, each of the two subsets and the another set are input to the same mapping function to generate three equal size sets of modulation symbols which are transmitted via the DCCH segment. Uplink tone hopping is used such that one of the equal size sets of modulation symbols for the DCCH segment uses the same tone but a different set uses a different tone.

    摘要: A flexible and relatively hardware efficient LDPC decoder is described. The decoder can be implemented with a level of parallelism which is less than the full parallelism of the code structure used to control the decoding process. Each command of a relatively simple control code used to describe the code structure can be stored and executed multiple times to complete the decoding of a codeword. Different codeword lengths are supported using the same set of control code instructions but with the code being implemented a different number of times depending on the codeword length. The decoder can switch between decoding codewords of different lengths, without the need to change the stored code description information, by simply changing a code lifting factor that is indicative of codeword length and is used to control the decoding process. When decoding codewords shorter than the maximum supported codeword length some block storage locations may go unused.

    摘要: A device includes a zero symbol rate (ZSR) coding/modulation module and a second type coding/modulation module. Both modules generate modulation symbols to be conveyed using the same air link resources but with the non-zero ZSR symbols having a higher power level. The ZSR module generates a mixture of zero and non-zero modulation symbols. A ZSR modulation scheme communicates information using both the position of the non-zero modulation symbols and the phase and/or amplitude of the non-zero modulation symbols. Different ZSR schemes, implementing different ratios relating the number of zero symbols to the total number of symbols, can be associated with different low data rates while second module modulation schemes can be associated with different high data rates. Modulation symbols from two modules are in some embodiments, superimposed. In some embodiments, non-zero ZSR modulation symbols punch out second module modulation symbols which occupy the same air link resource.

    摘要: A wireless terminal includes an uplink rate option indicator in the same uplink channel segment with data, the rate option indicator providing transmission rate information about the data transmitted in the segment. The indicator value is represented by an energy pattern within the segment. Different energy patterns correspond to different indicator values. The number of indicator values is less than the number of possible uplink data rate options supported by the wireless terminal. A single indicator value represents different uplink data rate options, at different times, as a function of a received maximum data rate option and/or type of assignment message. The maximum data rate option and/or assignment message was transmitted by the same base station receiving the indicator value; therefore, there is no ambiguity between wireless terminal and base station as to the interpretation of the uplink data rate option indicator value with respect to an individual uplink segment.

    摘要: The claimed subject matter relates to enabling antenna switching in a wireless terminal that has multiple receive antennas per receive chain via soft-demodulation and interleaving of concatenated code received in a strip channel. A coherent demodulation protocol may be performed to estimate an SNR for a first antenna during a first time period, and a non-coherent demodulation protocol may be utilized on the strip channel to estimate an SNR for at least one other antenna during a second time period. SNRs may be compared and the terminal may select the antenna with the highest SNR for a next transmission superslot.
