摘要： Techniques are provided for a radio link quality monitoring method and an user equipment, such that a given user equipment device (UE) receives a plurality of Orthogonal Frequency Division Multiplex symbols that comprise a plurality of resource elements distributed in time and frequency, and which include reference symbols. The objective of the radio link quality monitoring is to predict the user equipment detection probability of control messages transmitted by a base station (BS). The radio link quality estimation process calculates two average signal to noise ratio values over the complete frequency bandwidth for two assumed control channel formats corresponding to in-sync and out-of-sync conditions. The results of the calculations are then used to deduce the average error probabilities that are compared with predefined thresholds to provide the in-sync/out-of-sync indications.

摘要： Techniques are provided herein for the offline static analysis of a stable code base in order to build a compiler and tools specialised to that code base. This allows global code base knowledge to be applied earlier in the compilation process giving better opportunities for optimisation. The offline static analysis produces specialized compiler components that are then used to rebuild the compiler. This results, over time, in a compiler specialized to the code base with improved optimization after every compiler release cycle.

摘要： A Viterbi trellis processing technique in which soft decisions and hard decisions are derived from a received signal and the soft decisions are enhanced by being modified using the hard decisions. A log likelihood ratio for a bit of the received signal can be derived by grouping candidate metrics associated with the decision that the bit has a first state, grouping candidate metrics associated with the decision that the bit has a second state, applying respective functions to the groups and calculating the difference of the function values.

摘要： Techniques are provided aimed at improving the flexibility and reducing the area and power consumption of digital baseband integrated circuits by using stream data processor (210) based modem architecture. Semiconductor companies offering baseband ICs for handsets, face the challenges of improving die size efficiency, power efficiency, performance, time to market, and coping with evolving standards. Software defined radio based implementations offer a fast time to market. Dedicated hardware designs give the best die size and power efficiency. To combine the advantages of dedicated hardware with the advantages of conventional software defined radio solutions the stream data processor (210) is partitioned into a stream processor unit (410), which implements processing functions in dedicated hardware and is hence die size and power efficient, and a flexible stream control unit (430) which may be software defined to minimize the time to market of the product.
