signal subspace algorithms are compared with competitive noniterative techniques. A justification is given for choosing techniques, such as the MUSIC algorithm, to maximize discrimination performance in a point-target scenario. A direct theoretical comparison with the Capon and Burg method is given, using the concept of a modified covariance matrix. The special case of complex sinusoids is examined in detail. The difficulty of including collateral knowledge to directly control the choice of solution is discussed. Examples of simulation results are given for cases where strong signals potentially dominate weaker components in the data.

Current developments in weather instrumentation, particularly the modern weather radar, are discussed, and the characteristics of air traffic control (ATC)-dedicated weather radars are examined. It is pointed out that the future ATC weather radar will be of the pulse-Doppler type, with efficient clutter rejection and parameter estimation functions. Quantitative indicators of performance parameters are provided, and directions of research in signalprocessingalgorithms and data processing software are charted. Considerations for optimization displays and current effort in that direction are summarized. Possible steps toward automated weather avoidance are discussed.

A 7 kHz-band speech CODEC using an advanced digital signal processor is developed. The coding algorithm for this CODEC requires greater processing power due to its complexity and high sampling rate. A high-performance digital signal processor VLSI, "DSSP-1", is applied to this CODEC. Arithmetic word-length, arithmetic operation speed, and memory capacity required for this CODEC is evaluated. DSSP-1 can satisfy these requirements; this CODEC has been built with two DSSP-1 chips and several memory chips.

In this paper, a forward/backward adaptive digital filtering method is studied for the enhancement of noisy speech. The enhancing algorithm uses future samples as well as previous samples to estimate a current sample, and utilizes the correlational property of speech. It is effective for the enhancement of narrow-band as well as wide-band noisy speech. To improve the enhancing capability further, its modified version is also considered. This modified algorithm, of which structure is relatively simple, works for any kind of additive noise, and results in signal-to-noise ratio gain over existing enhancement algorithms by about 2 dB.
