While turbo coding techniques have received much recent attention for their extraordinary coding gains, these techniques inherently suffer latency limitations unacceptable in most telephony applications. Long constraint length (LCL) Viterbi decoding

A new quantization scheme is presented for truncating the values of a high precision digital sequence to only a few non-zero bits. Sigma-delta modulation is used to round values to the nearest n-bit canonic signed-digit code (number representable as

Ratio cut hierarchical partitioning, which enables efficient multilevel simulated annealing, is applied to the row placement problem for large circuits. An overlapping moving window scheme is used to compensate for the effect of partitioning on the p

Quality assessment is crucial to developments of video communication systems. While subjective test yields most accurate results, its expensive cost and human biasness make it an unsatisfactory figure of merit. The peak-signal to noise ratio (PSNR),

This paper presents a time reversal based noncausal IIR filtering scheme which offers significantly fewer operations than similarly performing causal approaches. This new scheme improves on previous multi-pass approaches by using single-pass overlap-

A technique for increasing the accuracy of attitude update calculations when data sample rates are low is described. The technique is based on the use of a fixed-point coordinate rotation digital computer (CORDIC) function. In addition to improved ac
