History and Development of Turbo Product Code
Turbo Product Code, often referred to as TPC, is a powerful error-correction coding scheme that has revolutionized modern communication systems. TPC was first introduced in the early 1990s as a groundbreaking advancement in the field of coding theory.
Origin and early research
The concept of Turbo Product Code emerged from the collaborative efforts of a group of researchers at the University of California, Berkeley, and Qualcomm Inc. Their goal was to develop a coding scheme that could effectively correct errors in data transmissions over noisy communication channels.
Advancements and improvements over the years
Since its inception, Turbo Product Code has undergone significant advancements and improvements. Researchers have continuously refined the encoding and decoding algorithms, improving the code’s error correction capabilities and overall efficiency.
How Turbo Product Code Works
Turbo Product Code operates through a process known as parallel concatenation of convolutional codes. This involves interleaving two or more convolutional codes in parallel, creating a more robust and efficient error-correction mechanism.
Encoding process
In the encoding process, the input data is encoded using multiple parallel convolutional encoders. The encoded bits are then interleaved and combined to form the final Turbo Product Code sequence, which is transmitted over the communication channel.
Decoding process
On the receiving end, the Turbo Product Code sequence is decoded using iterative decoding algorithms. These algorithms iterate between the constituent decoders, exchanging extrinsic information to improve the overall decoding performance and correct errors in the received data.
