Global unified session identifier across multiple data centers
Systems and methods are disclosed for using a global unified session identifier across data centers. When a user first accesses a data center and an initial session is created for the user in the data center, a session identifier is generated for the user session.

Virtualization of natural radio environments to test a radio device
Natural radio environments are virtualized to test radio devices. In one example, this is done by extracting signals and messages recorded in the field and injecting them in the operation of a protocol tester. In another example, the radio environment is reproduced by generating channel impulse responses in a ray-tracer, then interpolating them in a channel emulator and supporting the interpolation by means of post-processing. In another example, the radio environment is recorded using a mobile terminal in the field.

Margin test methods and circuits
Described are methods and circuits for margin testing digital receivers. These methods and circuits prevent margins from collapsing in response to erroneously received data, and can thus be used in receivers that employ historical data to reduce intersymbol interference (ISI).

Also described are methods of plotting and interpreting filtered and unfiltered error data generated by the disclosed methods and circuits.

A low cost, high reliability system for correcting aberrations in optical signals is disclosed.

Reducing switching error in data converters
In some converter architectures, unary digital-to-analog (DAC) converter elements generate an analog output which represents the digital input signal. Thermometer codes trigger an appropriate number of DAC elements to generate the analog output. The DAC elements are not all perfectly weighted, and mismatch shaping is often used to dynamically equalize the usage of each DAC element during data conversion to average out the mismatches. Unfortunately, mismatch shaping adds additional switching and can worsen the effect of switching errors. Switching errors which are non-linearly dependent on the input causes a second order distortion if the sum of the switching errors corresponding to a set of DAC elements is not zero. Prior to data conversion, calibration can select a subset of DAC elements having a lesser sum of switching errors for data conversion. Other (redundant) DAC elements are not used at all or shut off permanently. |
