摘要： In 3GPP LTE, user equipment must be able to report reference signal received power (RSRP) measurement to the serving cell's base station. A low-complexity method for asynchronous RSRP measurement in an LTE user equipment receiver is provided which includes frequency shifting the received signal so that the upper or lower half band becomes centered around the DC frequency; decimating the received signal to a width of n·2m samples, n being the reference symbol spacing in the received signal; dividing the samples into n sample vectors with a length of 2m each, superimposing the n sample vectors; and performing FFT operation on the superimposed signal.

摘要： A low complexity method for determining a search sequence of nodes for an efficient soft-decision sphere decoding algorithm for use in receivers for quadrature amplitude modulation (QAM) communication signals is achieved by determining a first member of the search sequence by rounding a received symbol (z) to a first constellation symbol (xc) of the QAM constellation, classifying the remaining constellation symbols (xi) of the QAM constellation into a plurality of sub-sets of constellation symbols having the same distance metric relative to said first constellation point (xc) according to a metric dsequ(n)=2a·n=max{|real(xc−xi)|,|imag(xc−xi)|}, a being a scaling factor of the constellation grid, and ordering said sub-sets of constellation symbols in ascending order of their distance metric relative to the first constellation symbol (xc), and ordering the members of each sub-set of constellation symbols that are defined by the same distance metric according to their Euclidean distances.

摘要： A method is provided for decoding data packets in wireless communication schemes that use a Hybrid Automatic Repeat Request technique, and a receiver for wireless communication that performs such a method. The HARQ memory incorporated in a receiver for wireless communication is minimized to a size which only reserves memory for an average number of erroneous sub-packets. Following decoding, an error check is performed on a per sub-packet basis, and only the softbits of those sub-packets for which decoding errors have been detected are stored in the HARQ memory. Correctly decoded sub-packets are stored in a separate memory. This significantly decreases the size of the HARQ memory required at the receiver which is beneficial in terms of both silicon area and power consumption.

摘要： A mobile station receiving a signal from a base station experiences time/frequency varying channel conditions. In order to get the maximum throughput from a base-station, it is necessary to adjust the modulation and coding schemes to the actual channel quality. To do so, mobile receivers are required to probe the radio channel condition and feedback a limited set of estimated channel state information parameters such as CQI, RI, and PMI. The invention uses modulation-specific mutual information as a basic metric for CQI-PMI-RI computation to yield high bandwidth efficiency under both flat fading and interference conditions as well as time and frequency selective fading and interference conditions, at reasonable complexity.

摘要： A circuit arrangement includes a plurality of functional units each of which comprises a plurality of data processing modules and a local controller. The plurality of data processing modules run a common system clock and are connected by a streaming data bus running a handshake-type streaming data transfer protocol. A profiling module of the circuit arrangement assesses control signals tapped at predefined interfaces of the streaming data bus during real time operation, for determining link performance and communication patterns for profiling and debugging purposes, and hence constitutes a simple and low cost approach for assessing intra-component and inter-component link performance and communication patterns on large SoCs. A method for profiling data flow for use in such a circuit arrangement is also provided.

摘要： A hardware accelerator module is driven by a system processor via a system bus to sequentially process data blocks of a data stream as a function of a parameter set defined by the processor. The module includes a register block adapted to receive parameter sets from the system processor, an accelerator core adapted to receive streaming data, to process data blocks of said streaming data in a manner defined by a parameter set, and to output processed streaming data, and a parameter buffering block adapted to consecutively store a plurality of parameter sets and to sequentially provide the parameter sets to the hardware accelerator core as a function of a busy state of the hardware accelerator core. The parameter buffering block enables to reduce downtimes of hardware accelerators, to increase data throughput, and to reduce the risk of a processor overload in a processor which drives several hardware accelerators.
