ECC is accomplished by adding redundancy to the transmitted information using an algorithm. A redundant bit may be a complicated function of many original information bits. The original information may or may not appear literally in the encoded output; codes that include the unmodified input in the output are systematic, while those that do not are non-systematic. A simplistic example of ECC is to transmit each data bit 3 times, which is known as a (3,1) repetit… WebPursuit scheme. The coding artifacts are less annoying than the ringing introduced by wavelets at very low bit rate, due to the smoothing performed by the basis functions used in the MP algorithm. In addition to good compression performance at low bit rate, the new coder has the advantage of producing highly e xible scalable streams.

WebA compressed message has less redundancy. Shannon's source coding theorem states a lossless compression scheme cannot compress messages, on average, to have more than one bit of information per bit of message, but that any value less than one bit of information per bit of message can be attained by employing a suitable coding scheme.

For typical SPIHT coding rates (1/4–1/2 bpp), the total added redundancy relative to the total generated bits is less than 10%, and the fixed-size level-2 redundancy (sign bits) is even smaller. In contrast, the MD-SPIHT method proposed in [6] introduces 20% redundancy at 0.5 bpp. bin pan shale wettability
