All IPs > Wireline Communication > Interleaver/Deinterleaver
In the realm of wireline communication, interleavers and deinterleavers play a crucial role in ensuring data integrity and enhancing signal reliability. These components are vital in the preprocessing of data, often used in communication protocols to rearrange digital signals, which enables the system to counteract errors introduced during data transmission. Interleaver/Deinterleaver semiconductor IP solutions are designed to offer this functionality in a highly efficient manner, frequently optimizing the performance of digital communication systems.
The main function of an interleaver is to rearrange input data into a non-sequential order before transmission. This process effectively disperses error bursts that commonly occur in wireline communication. When these errors are scattered across the data stream, they become easier to manage and correct using error correction codes. On the other side of the transmission, a deinterleaver reassembles the data back into its original sequence, ready for decoding and further processing.
Interleaver/Deinterleaver semiconductor IPs cater to various applications in communications like DSL, fiber optics, and other high-speed data transmission technologies. By facilitating this reordering process, these IPs help ensure that the communication link maintains high fidelity even in environments susceptible to noise and interference. This capability is invaluable for maintaining robust and reliable connections, which are essential in applications ranging from internet infrastructure to enterprise networking solutions.
Products in this category are engineered for performance and scalability, accommodating the needs of both consumer and industrial-grade technologies. This includes supporting diverse data rates and modulation techniques, which are critical in optimizing the transmission capabilities of wireline systems. Through these highly specialized semiconductor IPs, developers can integrate advanced error management and correction methods, ultimately enhancing the overall efficiency of the communication systems they are designing.

On the transmitter side, the turbo -phi encoder architecture is based on a parallel concatenation of two double -binary Recursive Systematic Convolutional (RSC) encoders, fed by blocks of K bits (N=K/2). It is a 16-state double-binary turbo encoder. On the receiver side, the turbo decoder engine is built using two functioning soft-in/soft-out modules (SISO). The outputs of one SISO, after applying the scaling and interleaving are used by its dual SISO in the next half iteration. Both the turbo encoder and decoder are fully compliant with the DVB-RCS2, supporting all its code rates and block sizes. In order to achieve higher throughput, the turbo decoder uses parallel MAP decoders. The sliding window algorithm is used to reduce the internal memory sizes. Turbo decoder accepts input LLR’s and outputs the hard decision bits after completing the decoder iterations.
