摘要:
A method (1700) and apparatus (1801) provide channel estimation with extended bandwidth filters. Antenna (1813) receives a signal such as a pilot signal and detects a bandwidth associated with the pilot signal in a detector (320). One of a plurality of filters (603, 605, 607, and 609) including extended bandwidth filters (311) and a default filter (305) can be selected by a selector (617). If the detector detects activity associated with a wider bandwidth, the filter associated with the wider bandwidth is selected over the presently selected filter. If no activity is detected, the default filter is selected.
摘要:
The present invention relates to aqueous pesticide formulations containing high concentrations of a herbicide, such as the potassium salt of glyphosate, together with surfactants or other adjuvants, including formulations which form anisotropic aggregates (AA) or liquid crystals (LC) on or in the foliage of a plant. More specifically, the present invention relates to glyphosate containing herbicidal formulations containing one or more surfactants that form anisotropic aggregates and/or liquid crystals to facilitate the introduction, uptake and translocation of glyphosate throughout the plant. Methods of killing or controlling unwanted vegetation using such formulations are also described. The invention also relates to novel surfactants and pesticide compositions containing such surfactants.
摘要:
A base station receives (201) OFDMA messages from a plurality of end user platforms that share all used tones within at least one OFDMA symbol. By one approach this base station then uses (202) a fixed starting time to select contiguous samples from received aggregate multi-user signals wherein the fixed starting time is offset from a reference time that comprises a time at which the base station expects to be receiving the signals from all end users. In combination with the time offset approach noted above or in lieu thereof the base station can process (204) selected contiguous samples using fast Fourier transform and then provide (205) phase rotation with respect to those processed samples. When applying phase rotation, by one approach a phase rotation can be applied (401) to the aggregate multi-user signal and, in addition, individual phase rotation can be applied (402) as determined on a user-by-user basis.

摘要:
A wireless transceiver (100) that produces soft decisions for received, block error correction encoded codewords and a confidence indicator signifying a likelihood of errors in the detected data. The wireless transceiver (100) processes block encrypted signals, such as feedback channel messages in a WiMax uplink. Upon receiving a signal, a soft decision is determined for received block encoded codewords. A difference is calculated between a soft decision metric for a most likely detected codeword and a soft decision metric for a next most likely detected codeword. This difference is normalized based upon the total decoder input power received over the received signal (201 ). The normalized difference is then scaled by a channel dependent factor and is time filtered. The normalized and time filtered confidence indicator output (212) is able to be provided to a wireless network controller to assess the usability of the received data.
