Abstract: The present invention relates a method, apparatus, receiver, computer program for joint detection. In the method, it is firstly determined if whether a number of original active codes is beyond a predefined threshold or not, and when the number of the original active codes is beyond the predefined threshold and a strong interference code exists in the active codes corresponding to intra-frequency adjacent cells, it is to apply an interference cancellation to a receive signal, cancel MAI caused by a strong interference signal corresponding to the strong interference code, and perform a joint detection by utilizing a matched filtering result of a remaining signal after the interference cancellation for the joint detection. According to at least one embodiment of the present invention, when there is large interference in the intra-frequency adjacent cells and the number of the active codes is beyond a maximum threshold, the joint detection performance is improved.

Abstract: A clock signal for electronic circuitry is generated by generating, based on which one of a plurality of application use cases is presently active, a first signal that indicates a first selected one of a plurality of clock signal operating points. Based on the electronic circuitry's present speed requirement, a second signal is generated that indicates a second selected one of the clock signal operating points. For any given one of the application use cases, the speed requirement need not remain constant for the duration of the application use case. Based on whichever one of the first and second signals is associated with a higher clock frequency operating point, a third signal is generated that indicates which clock signal operating point (and possibly what voltage level) should be active. The third signal controls generation of a clock (and possibly also voltage level).

Abstract: Multiple-input multiple-output (MIMO) with multiple power amplifiers and antennas in a mobile transmitter, such as a user equipment for a cellular telephone communication system, has such great impacts on the transmitter's battery life, form factor, and complexity that it should not be used unless its benefits clearly outweigh its costs. Methods and apparatus enable the benefits of MIMO by beam-forming and antenna-switching to be obtained without incurring the drawbacks of increased current consumption due to multiple power amplifiers.

Abstract: The present invention relates to a method, an apparatus, a receiver, a computer program and a storage medium for joint detection. The method comprises: adjusting a ranking order of codes in a matched filtering result and a ranking order of column vectors in a system submatrix according to the power, performing the joint detection using an adjusted matched filtering result and an adjusted system submatrix, and acquiring demodulated signals corresponding to the codes. The codes having high power will be demodulated firstly, thus it ensures accuracy of demodulation, inhibits erroneous propagation effect and improves accuracy of the joint detection.

Abstract: An intermediate symbol buffer (ISB) configuration and method is provided such that the ISB memory comprises 15 portions, one for each HSDPA spreading code. Symbols associated with a spreading code are written to the memory portion associated with the same spreading code. When a covariance calculation is performed to obtain a more accurate channel estimate, only the symbols associated with spreading codes determined to be needed for the covariance calculation are written to the ISB by a buffer block and red from the ISB by a correlation core. The symbols associated with spreading codes that are not necessary for a covariance calculation may be masked from being written or read from the ISB. In some embodiments each memory portion is an individual memory block. In other embodiments a plurality of memory blocks may contain a plurality of memory portions, one memory partition designated, at least temporarily, or each spreading code.
