20180375518 | High-Speed MOSFET and IGBT Gate Driver - A gate driver integrated circuit drives an output signal onto its output terminal and onto the gate of a power transistor.

In other words, the word positions are effectively checked without a prior assumption as to which words are the first and last of the code. This reduces the task to the number of different bit-alignments possible within a single data word, rather than the number of bit-alignments possible in a complete FEC code. In one implementation, the lock time is reduced by approximately 50 times when compared to a straightforward solution. | 2018-12-27 |

20180375615 | GENERATION OF POLAR CODES WITH A VARIABLE BLOCK LENGTH UTILIZING PUNCTURING - Polar codes may be generated with a variable block length utilizing puncturing. Some puncturing schemes consider punctured bits as unknown bits, and set the log likelihood ratio (LLR) for those bits to zero; while other puncturing schemes consider punctured bits as known bits, and set the LLR for those bits to infinity. Each of these puncturing schemes has been observed to provide benefits over the other under different circumstances, especially corresponding to different coding rates or different signal to noise ratio (SNR). According to aspects of the present disclosure, both puncturing schemes are compared, and the puncturing scheme resulting in the better performance is utilized for transmission. | 2018-12-27 |
20180375616 | TELECOMMUNICATIONS APPARATUS AND METHODS - A method of transmitting a block of data from a transmitter entity to a receiver entity in a wireless telecommunication system. The method includes: establishing a plurality of different redundancy versions for the block of data; transmitting the plurality of different redundancy versions for the block of data in a first sequence order in a first time period; and transmitting the plurality of different redundancy versions for the block of data in a second sequence order in a second time period, wherein the second sequence order is different form the first sequence order. | 2018-12-27 |
20180375617 | METHOD AND DEVICE FOR RETRANSMISSION - Embodiments related to retransmission in a communication system are described and depicted. In one embodiment, a retransmission entity repeats a transmission of a data transfer unit by the device after a predetermined number of other transmitted data transfer units has been transmitted. The retransmission entity may also determine whether a measure for a time period since the first transmission of the data transfer unit by the device has exceeded a predetermined threshold and to provide a final transmission of the data transfer unit based on the determining that the measure for the time period has exceeded the predetermined threshold. | 2018-12-27 |
