Title: Forward error correction on multiplexed cdma channels enabling high performance coding
Inventor: PROCTOR JAMES A JR
IPC: H04L47/43
Filed: 2000-02-23
Granted: 2012-07-31
Abstract: A protocol for optimizing the use of coded transmissions such as over wireless links. In this technique, interframes are first split into segments selected to be an optimum size according to transmission characteristics of the radio channel. Segments are assigned a position identifier and redundancy check sum. Segments are then assembled into blocks and a forward error correction algorithm is applied to the block to generate redundancy bits. The FEC block is then split up among available communication channels and forwarded to the receiver. The inverse process is applied at the receiver. Using this scheme, only segments containing erroneous data need to be resent. A large block size required for high performance forward error correction may therefore be used while at the same time minimizing latencies associated with the need to resend entire blocks when errors cannot be recovered.

Abstract: Systems and methods to detect a failure of a subset of component power packs within a multiple component rechargeable power pack. At least one parameter of a charging current that is provided for a time duration to a rechargeable power pack is determined. A measured capacity change quantity for the rechargeable power pack during the time duration is estimated. The measured capacity change quantity is compared, after the time duration, to an expected capacity change quantity that is based upon the at least one parameter. A determination is made that at least one component power pack within the rechargeable power pack has failed based on a difference between the measured capacity change quantity and the expected capacity change quantity. A charging current parameter is modified in response to the determining that the at least one component power pack has failed.
