Latest Patents

One of his latest patents is titled "Soft bit computation for a reduced state equalizer." This invention presents a method and apparatus for soft bit computation that reduces the number of states in the equalizer, ensuring acceptable complexity while performing soft bit computation for nearly all bits. The method involves computing a first set of soft bits from transmitted bits in a received signal, utilizing a reduced-state trellis with finite non-zero delay. It also includes calculating hard decisions based on the received signal and employing zero-delay soft decision-making to compute a second set of soft bits. The hard decisions are instrumental in this computation process.

Another significant patent is "Wireless telecommunication system having improved recognition of modulation type in GPRS." This method operates a wireless mobile station to receive a time slot sent through a radio channel from a transmitter. In this GPRS embodiment, the time slot consists of a Header portion and a Data portion. The Header portion specifies whether the Data portion is modulated using 8-PSK modulation or π/4-shifted DQPSK modulation. The method includes steps for estimating the quality of the radio channel, determining detection error magnitudes, calculating mean detection error powers, and selecting the modulation type based on comparisons with threshold values.
