摘要： In a DOCSIS based satellite gateway data is transmitted over a single downstream channel, at different throughput rates. Data destined for each subscriber/receiver is assigned a throughput rate depending upon the downstream signal quality of that subscriber/receiver. To accomplish this, the downstream DOCSIS MAC data is parsed to extract DOCSIS packets. The DOCSIS packets are then loaded into packet queues based on an identifier within such packets such as the MAC destination address or SID. Each of the queues represents a bandwidth efficiency or throughput rate that can be currently tolerated by specific subscribers based on the current signal quality being experienced at the subscriber location. A PHY-MAP describing the downstream data structure to be transmitted and inserted into the downstream data. Data is extracted from the packet queues in queue blocks as defined by the PHY-MAP. The queue blocks are modulated with transmission parameters appropriate for each queue block and transmitted to the DOCSIS based satellite modems. The satellite modems extract the PHY-MAP from the downstream data and use the information contained in it to demodulate and decode the queue for which they have sufficient downstream signal quality. Satellite modems measure and transmit downstream signal quality to the satellite gateway to be used to assigned traffic to the appropriate queues.

摘要： A communications system, having a combination Reed-Solomon encoder and a Turbo-Code encoder Data frame configuration which may be changed to accommodate embedded submarkers of known value are embedded in with the data order to aid synchronization in the receiver system, by providing strings of known symbols. The string of known symbols may be the same as the symbols within a training header that appears at the beginning of a data frame. Frame parameters may be tailored to individual users and may be controlled by information pertaining to receivers, such as bit error rate, of the receiver. Additional headers may be interspersed within the data in order to assist in receiver synchronization. Frames of data may be acquired quickly by a receiver by having a string of symbols representing the phase offset between successive header symbols in the header training sequence in order to determine the carrier offset. Phase lock to a signal may be achieved after determining carrier offset in receivers by correlating successive symbols in successive headers. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

摘要： A CMOS circuit formed in a semiconductor substrate having improved immunity to radiation induced latch-up and improved immunity to a single event upset. The circuit architecture of the present invention can be utilized with N-Well, P-Well and dual Well processes. For example, the circuit is described relative to an N-Well process. An N-Well is formed in a p-type substrate. A network of p-channel transistors are formed in the N-Well and a network of n-channel transistors are formed in the p-type substrate. A continuous P+guard ring is formed surrounding the n-channel transistors and between the n-channel transistors and the N-Well. Similarly, a continuous N+guard ring is formed surrounding the p-channel transistors and between the p-channel transistors and the p-type substrate. In the event of a radiation hit, the guard rings operate to reduce the parasitic impedance in the collector circuits of the parasitic bipolars forming a parasitic SCR and also act as additional collectors of radiation induced current. Single event upset immunity is improved by forming duplicate functions in an n-channel network and a p-channel network. N-channel control transistors are coupled to control p-channel load transistors and p-channel control transistors are coupled to control n-channel load transistors.

摘要： The present invention provides an SEU immune solution which minimizes the disadvantages of the increased weight and size of prior art SEU immune circuits. In the present invention, the SEU immune solution can comprise two portions. First, a control portion can be comprised of SEU tolerant electronics as described in the prior art. A processor comprises the second portion and is preferably not SEU immune. The present invention makes it unnecessary for both portions of the circuit to be comprised of SEU tolerant logic in order for the output of the present invention to be SEU tolerant. In particular, the present invention is especially well suited for outer space travel since the present invention will not be upset by SEUs and retains a small package size and light weight.

摘要： A method and apparatus for decoding Reed-Solomon codes in large Galois Fields GF(2.sup.n) represents the finite field as a quadratic extension field of one or more subfields GF(2.sup.m). This type of field representation allows embedded subfields, as well as the primary extension field to be simultaneously represented in normal form. The basic arithmetic operations for the extension field are written solely in terms of operations performed in one or more subfields. The operations of multiplication, inverse, square, square root and conjugation are performed in GF(2.sup.n), utilizing only operations from the subfield GF(2.sup.m).
