A system and method for patient control of the stimulation parameters of a Spinal Cord Stimulation (SCS) system, or other neurostimulation system, provides an increased Therapeutic Ratio (TR). Measurements of the just-perceptible stimulation level and the maximum-comfortable stimulation level are made for at least two values of pulse duration and two values of pulse amplitude. A Therapeutic Ratio is determined for stimulation level control strategies based on fixed pulse duration and variable pulse amplitude, and alternatively for fixed pulse amplitude and variable pulse duration. The control strategy providing the greatest therapeutic ratio is then selected for use by the patient. In an alternative embodiment, the pulse durations at the just-perceptible and maximum-comfortable stimulation levels are measured, and the pulse amplitudes at the just-perceptible and maximum-comfortable stimulation levels are determined using a curve-fitting process. Similarly, the pulse amplitudes may first be measured and the pulse widths determined using a curve-fitting process.

A class of n×l nonlinear block codes, termed Go-CDMA codes are constructed using column-reduced and row-reduced Hadamard orthogonal matrices, termed Go-CDMA matrices. Here n,l are positive integers: n chips of user data are transmitted in frames of size l≦αn, where α is the frame expansion factor. The codes map n-vectors containing binary message data to binary or multi-level l-vectors for transmission, where l≧n. The codes are invertible maps for the binary message data, and when there is no message data in some input vector elements, and noise added between the coding and decoding, there is some error correction. The coding uses integer arithmetic and integer quantization operations, preferably certain sign operations. Go-CDMA codes may be implemented in CDMA communication systems to improve performance on many measures over conventional CDMA and TDMA systems. The coding and decoding may include scrambling and descrambling the Go-CDMA coded signal based on random codes.

A method and apparatus is provided that yields improved performance of both single channel and WDM long-distance optical transmission systems by synchronously modulating of the transmitted signal's amplitude. An amplitude modulator receives an optical signal onto which data has been modulated at a predetermined frequency.
