Telecommunications evolution

1. Network transformation (e.g. time-based switches to packet-based switches).
2. Service providers transformation (e.g. voice and limited data service on public switched telephone network (PSTN) vs. voice and broadband-based voice and data on fixed and wireless networks).
3. Service transformation (e.g. voice over copper to voice over IP networks, TVs over IP networks, tele-video conferences).

Data representation

To represent a source of data in a compact form
1. Using the affine transform
2. Using the fractal transform
3. Using the Fourier transform
4. Using the wavelet transform

Transform coding

1. Divide the sequence {x_n} into N blocks. Each block is mapped into a transformed sequence using a reversible mapping.
2. Quantizing the transform sequence. The quantization strategy depends on three main factors: the desired average bit rate, the statistics of the elements of transformed sequence and the effect of distortion in the transformed sequence on the reconstructed sequence.
3. Encode the quantized values using some binary encoding technique.
