Disclosed is an apparatus and a method for actively adjusting the quantization interval of signals inputted to a decoder in a digital communication system. The apparatus includes a quantization level generator for measuring a dynamic range of received packet data and calculating a corresponding scale ...

There is a cost in terms of the number of bits required to describe the quantizer output to a decoder, however, and arbitrarily reliable reproduction will not be possible for digital storage and communication media with ?nite capacity. A simple method for quantifying the cost for communications ...
An Overview of Digital Communication and Transmission 4.4.2 Quantization In Figure 4.10, each pulse is expressed as a level from a finite number of predetermined levels; each level can be represented by a symbol from a finite alphabet. The pulses in Figure 4.10 are called quantized samples. Whe...
length; in nonuniform quantization, regions of various lengths are allowed. It is clear that, in general, nonuniform quantizers outperform uniform quantizers.

For instance, its communication and computational overhead in edge computing scenarios is often excessively high, hindering real-time applications. This paper proposes an innovative federated learning framework, Q-Chain FL, integrating quantization compression techniques into a chained FL architecture. This...

Non-uniform quantization usually falls in the scope of the Code-Book mapping. NC (Natural Compression) [84] uses uneven quantization levels to round the value of an element to one of its two nearest integer powers of two. It is also an unbiased communication quantization method. The specific...
