Method for superimposing a sequence number in an error detection code in a data network
A system and method for superimposing a sequence number of a packet into the CRC segment of the packet thereby allowing more bandwidth in the payload portion of the packet for carrying data is described. Also described is a method of acquiring additional information on the type of error in a packet, e.g., data transmission errors or sequence errors, from analyzing a CRC error. For example, a reported CRC error can be the result of the receipt of a packet with a sequence number the receiver is not expecting (which is a normal occurrence on transmission links due to transmitters resending packets that a receiver has already accepted) or can result from a real error in the transmission of a packet. A first error code check (CRC) value is calculated for the payload segment of a data packet. A second CRC value is calculated for the sequence number of the data packet. The first CRC value and the second CRC value are combined thereby creating a third CRC value. The third CRC value is then combined with the payload segment of the data packet thereby creating a data packet that can be transmitted across the link.

Method and apparatus for link error prediction in a communication system
InactiveUS20050182994A1Error prevention/detection by using return channelError detection/prevention using signal quality detectorCommunications systemSignal-to-noise ratio (imaging)
A method is provided to accurately predict the probability of successfully recovering frames of (coded) information received over a wireless link, without having to decode the frame. This method, which consists of three steps, requires only limited information about the received signals and the forward error correction code and retransmission scheme being used. First, the signal to noise ratio (SNR) of each of the received signals is measured, where the average SNR is determined for multiple segments that together constitute the frame. Next, an algorithm is employed that takes these SNR values as inputs and determines the so-called effective SNR. The algorithm translates the measured SNR values using an appropriate convex metric, and subsequently combines the resulting values, thereby factoring in the effects of fading, multi-path, and other signal degradations. In the third stage, the effective SNR is used to determine the frame error rate by using a look-up table of a single reference curve that specifies the frame error rate of the actual error control code over an additive white Gaussian noise channel. This suffices to accurately predict the performance of a wide range of mobile communication channels. This method can be applied to a variety of retransmission strategies, including hybrid automatic-repeat request (ARQ) and incremental redundancy (IR) and combinations of these two strategies.

Programmable bit error rate monitor for serial interface
A programmable bit error rate monitor includes an error counter, a monitoring period counter with a programmable upper bound to set the monitoring period, and an error flag generator that compares the actual error count to a programmable threshold. The error flag generator may generate flags at different sensitivity levels, and the user may programmably select one of those flags. The three flags can be generated by independent comparators, or they can be extrapolated from the base error flag—e.g., by comparing only certain bits of the error count to corresponding bits of the threshold.
