A gating control signal is applied to a given FFE tap during the integration period to enable the given FFE tap during a portion of the integration period in which the gating control signal overlaps the integration period so as to effectively multiply the data signal input to the given FFE tap with an FFE coefficient value corresponding to a period of overlap between the gating control signal and the integration period. |

Receiver of binary offset carrier (BOC) modulated signals
Binary Offset Carrier (BOC) is the agreed modulation for signals of next generation Global Navigation satellite systems (GNSS). Compared to current phase shift keying (PSK) modulation by a code, there is a further modulation by a sub-carrier. There is a known major difficulty with BOC called ‘false lock’ where early/late gates settle on the wrong peak of the multi-peaked correlation function. This invention eliminates the problem by eliminating that correlation. Instead, a two dimensional correlation is tracked independently to realize a dual estimate. An unambiguous lower accuracy estimate derived from the code phase is used to make an integer correction to a higher accuracy but ambiguous independent estimate based on the sub-carrier phase. The actual receiver may adopt a triple loop, instead of the usual double loop, where carrier phase, sub-carrier phase and code phase are tracked independently but interactively. |

A method for contention-based (CB) uplink transmission in a wireless communication network is provided. A base station (eNB) first transmits CB configuration information and CB grant to a user equipment (UE).

Outphasing power amplifier linearization method with improved output power back-off efficiency
A high efficiency outphasing power amplifier is disclosed which provides a high-efficiency, high-linearity outphasing amplifier capable of amplifying complex, wideband, multi-tone signals. Systems herein may amplify at least 256 symbol QAM signals with negligible distortion, while achieving high direct current-to-radio frequency efficiency sustainable at virtually all power levels. Embodiments of the outphasing amplifier employ a bridge output network formed from two complementary Class-D amplifiers to switch a dc supply voltage across the load. In embodiments, the phase of both halves of the bridge is varied from zero to +/−90 or zero to 180 degrees to split the workload, to correct for phase error within the bridge network and to control output power. Because the current through the load and thus through the two halves of the amplifier vary directly with output level, the efficiency remains high even when power output is low. |

Load current sensing
Techniques for sensing current delivered to a load by a differential output stage, e.g., in a Class D amplifier. In one aspect, voltages across sense resistors coupled in series with first and second branches of the differential output stage are low-passed filtered and digitized. The sense resistors may be coupled in series with the sources of transistors of the first and second branches, wherein the transistors are selectively switchable on and off by input voltage driving voltages. The input driving voltages may correspond to a ternary voltage waveform such that during a given phase, the two transistors coupled in series with the sense resistors may be turned off. Further aspects provide for the first and second branches having cascoded NMOS and/or PMOS transistors, and the sense resistors being provided between a pair of cascoded transistors. |

Variable admittance circuit
A programmable variable admittance circuit may be used in a programmable filter or a variable gain amplifier in a number of different applications including tuners and other RF receiver circuits. A variable admittance circuit and operation is described including a number of switchable admittance elements arranged in parallel branches. The variable admittance circuit requires fewer transitions to change between successive admittance values than a binary weighted circuit and fewer branches for implementation then a thermometry admittance circuit. |
