    Abstract: An embodiment of the present invention is a modified inverted-F antenna for wireless communication. The antenna circuit includes a dielectric substrate having a first surface, a radiating stub on the first surface of the dielectric substrate, and a first ground plate on the first surface of the dielectric substrate to couple to ground. The first ground plate includes one or more grounded capacitive stubs spaced apart from the radiating stub. The one or more grounded capacitive stubs tune performance parameters for the antenna circuit.

    Abstract: In accordance with a detection method in a wireless communication system, an initial hypothesis for a starting position of a desired signal within a received wireless communication signal may be determined. The desired signal may have a conjugate symmetric property. At least one correlation value may be determined based on the initial hypothesis. The at least one correlation value may indicate the extent to which at least one sample sequence selected from the received signal has the conjugate symmetric property.

    Abstract: Providing for reduced complexity or improved accuracy in de-mapping received wireless data streams for multi-channel wireless communication is described herein. By way of example, a low-complexity likelihood algorithm can be employed to de-map data bits from the wireless data streams. In one particular example, the likelihood algorithm can approximate a received bit with a subset of received wireless symbols correlated the bit, reducing algorithm complexity. In other examples, a limited set of received wireless symbols can be employed for the subset, further reducing algorithm complexity. According to at least one other example, logarithmic terms of the algorithm can be approximated with non-logarithmic functions, such as a look-up table, series expansion, polynomial approximation, or the like. These approximations can enhance symbol de-mapping accuracy while maintaining or improving processing overhead for a wireless receiver.

    Abstract: Methods and apparatus are provided for increasing throughput in a wireless communication system by reducing the amount of overhead transmitted to certain user terminals. Overhead due to control information may be reduced for these certain user terminals by selecting a low repetition factor. Overhead may be further reduced for these certain user terminals by selecting a modulation/coding scheme with a higher data rate for transmitting the control information. The selection may be based on channel conditions associated with the user terminals, such as signal-to-interference-plus-noise ratios (SINRs).
