Latest Patents

Ido Tal's latest patents focus on ECC polar coding and list decoding methods and codecs. One of his inventions describes a method of decoding data encoded with a polar code. This method involves decoding a received word of polar encoded data by following several distinct decoding paths to generate a list of codeword candidates. The decoding paths are successively duplicated and selectively pruned to create a list of potential decoding paths. Ultimately, a single decoding path is selected as the output, identifying a candidate codeword. In another embodiment, the polar encoded data includes redundancy values in its unfrozen bits, which assist in selecting the single decoding path. A preferred device for this invention is a cellular network device, such as a handset, that conducts decoding according to these methods.

Another patent by Tal involves methods and systems for decoding polar codes. This polar code decoder includes processing elements that receive pairs of input values and apply predetermined mathematical functions based on a control signal. It also features a first memory that stores outputs from processing elements and channel values related to the received polar code. Additionally, a second memory stores indices of frozen bits within the information-bit vector of the polar code being decoded. A computation block generates outputs that can be set to predetermined frozen values or calculated values, depending on whether the current index of the bit being decoded is frozen or not.
