GE IS200TSVCH2ADC MRP061873 module
In the current DSP market, communication devices are its largest users, and the following are a few examples:
(1) Digital honeycomb system
The digital honeycomb system uses a universal DSP to achieve functions such as speech synthesis, error correction coding, baseband modem, and system control.
a. Speech synthesis, speech compression, and encoding are the earliest and most widely used projects of DSP. In wired and wireless communication, vector encoders are used to compress speech signals into limited bandwidth channels.
b. Error correction coding. Forward Error Correction (FEC) schemes are widely used in telecommunications applications to reduce bit error rates in noisy channels. As more and more data passes through limited bandwidth channels, the demand for improved FEC technology becomes more urgent. Cyclic redundancy check (CRC) and bit parity check are still used for simple error detection. However, more complex forward error correction schemes, such as Verbi convolutional encoding and Reed Solomon (RS) encoding, are often used for multi bit error detection and correction. Usually, the encoding scheme for links is superior to simple schemes in reducing bit errors. For example, the IS-54 voice channel specification for digital honeycomb mobile phones in the United States is jointly guaranteed by CRC and convolutional codes.
