Based on the comparing a final time-alignment difference between the first signal and the second signal can be determined. At least one of the receiving, the calculating, the comparing, and the determining can be performed by at least one processor of at least one computing system.
In one aspect a computer-implemented method is performed. The method may include capturing intermediate data samples for transmission by a wireless communications transmitter. The method may further include applying signal processing to the intermediate data samples, capturing output data samples after applying the signal processing, and/or determining quadrature correction coefficients from the intermediate data samples and the output data samples, wherein the quadrature correction coefficients remove quadrature errors caused by the signal processing. The method may further include applying the quadrature correction coefficients to a series of input data samples, wherein the intermediate data samples comprise the input data samples with the quadrature correction coefficients applied to the input data samples. The capturing the intermediate data samples, the applying the signal processing, the capturing the output data samples, the determining the quadrature correction coefficients, and the applying the quadrature correction coefficients may be performed by at least one processor.

A method is presented which performs crest factor reduction (CFR) on a digitized signal. The method may include determining one or more peak values in a series of data samples of a communication signal, and/or generating a peak queue comprising the one or more peak values that exceed a threshold value and a corresponding index values for each peak value. The method may further include generating, from the peak queue, an entry to a clip table, the entry including a clip coefficient at the corresponding index value, updating the clip table to include a new clip coefficient at a new corresponding index value when the clip function squared at the new index value exceeds a scaled output power for an input power at the new corresponding index value, and/or clipping the series of data samples in a neighborhood of the peak value according to the clip function.
A system, a method, an apparatus, and a computer program product for transmission of data packets are disclosed. A determination is made whether an application service is being consumed by user equipment. Channel quality information is obtained for a channel being used by the user equipment to consume the application service. Based on the obtained channel quality information, a treatment is applied to the application service being consumed by the user equipment.

A receiver includes a first equalizer and a second equalizer. The first equalizer receiving a signal representing at least one symbol transmitted on an orthogonal frequency division multiplexing (OFDM) network by a first user equipment (UE) and at least one additional UE. The transmission is by the first UE to the receiver. The first equalizer computing, based on the signal, at least one first partially-equalized symbol of the first UE. The second equalizer is communicatively coupled to the first equalizer. The second equalizer receiving the at least one first partially-equalized symbols of the first UE, receiving at least one second partially-equalized symbol, and computing at least one equalized-symbol of the at least one first UE. The at least one second partially-equalized symbol is received from at least one additional base station being part of a coordinated multipoint (CoMP) group. Related apparatus, systems, techniques, and articles are also described.
