Abstract: A handheld computer system is disclosed. The handheld computer system includes a housing, a display supported by the housing, and a processor coupled to the display. The handheld computer system also includes a rechargeable battery configured to power the processor and the display. Further, the handheld computer system includes a recharging connector coupled to the rechargeable battery. Further still, the handheld computer system includes a recharger coupled to the recharging connector. Yet further still, the handheld computer system includes a radio frequency transceiver coupled to the processor and powerable by the battery when the battery has a charge above a predetermined low level, the transceiver configured to send and receive data while the battery charge is below the low level and the charger provides charge to the rechargeable battery and to the transceiver.

Abstract: A method for minimizing errors in a modulated signal transmitted over a transmission medium. The method is applied to the entire data block, thereby incorporating information about the parities of each row of data to fix and correct the errors in the row. Thereafter ISI removal is applied on a row by row basis, with such corrections being applied via soft decision coding. In particular, the data samples are first collected in a data block (or FEC block). A soft decision buffer is thereafter created by taking each sample involved. An FEC word is created by processing down each row of the soft decision buffer and creating a binary stream out of the sign bits for each table entry. This creates an estimate of the word by thresholding it around the zero level. A syndrome is generated via a comparison of the parity bits for each FEC word. The syndrome provides the most likely bit error positions, represented by an offset into the FEC word.
