In telephony, pair gain is the transmitting of multiple POTS signals over the twisted pairs traditionally used for a single traditional subscriber line in telephone systems. Pair gain has the effect of creating additional subscriber lines. This is typically used as an expedient way to solve subscriber line shortage problems by using existing wiring, instead of installing new wires from the central office to the customer premises. The term was invented in the middle 20th century by analogy with earlier use of gain to extend telephone local loops far from the telephone exchange.
A method for receiving burst signals in communication
This invention belongs to the field of communication technology, specifically a method for gain control of burst signal reception. First, it synchronously captures burst signal time-domain data and timing parameters, separates multipath components and extracts features, classifies environmental interference information, and finally fuses the time-domain, multipath, and interference data into a dataset, providing complete and multi-dimensional raw data support for subsequent signal feature analysis and gain decision-making. Then, based on the multi-dimensional acquired data, it calculates the dynamic range of signal amplitude to determine saturation risk, assesses the signal quality of multipath components to select effective components, quantifies the impact of interference on gain, and sorts gain requirements according to anti-saturation, multipath adaptation, and interference compensation, clarifying the core direction for hierarchical parameter decision-making. Based on this, this invention, through an optimized multi-dimensional acquisition and rapid feature analysis process, can significantly shorten the response cycle of gain adjustment, avoiding the loss of burst signals due to untimely adjustment.

Gain matrices for phase quantization
PCT designated stageWO2026107657A1Signalling characterisationWireless communicationPair gainUser equipment
Methods, systems, and devices for wireless communications are described. The described techniques may enable a user equipment (UE) to allocate bits of a phase quantization based on a relative gain increase of each of a set of amplitude values. For example, the UE may identify a gain matrix that defines a gain associated with allocating quantities of bits to each amplitude value. The UE may accordingly determine, for each bit of the phase quantization, a respective amplitude value to which the UE may allocate the bit. In some examples, the UE may be configured with multiple gain matrices associated with gain increases for multiple respective noise and source distributions. The UE may therefore select the gain matrix from the multiple configured gain matrices based on one or more noise measurements of the channel.
