چکیده
This paper presents search methods to optimize word-length for digital systems. Finding the word-length is tedious work when the variables for optimization are numerous. We have proposed sequential and preplanned searches to find out optimum wordlength, and compared them in terms of the trials. A comparison for a given optimized point is evaluated. We apply them to word-length optimization for a CDMA demodulator, of which requirement is FER of 0.03. Our results show the sequential and the preplanned search have reduced the trials by the rate of 64% and 89%, respectively compared to a full search to optimize the word-length for the CDMA demodulator design.

متن کاملMap Demodulator for Time-selective Fading Cdma Channels
A decision-feedback MAP receiver for time-selective fading CDMA channels is proposed. The receiver consists of a sequence-matched jilter and a MAP demodulator Output samples from the matched~lter are fed into the MAP demodulator The MAP demodulator exploits the channel memory by delaying the decision and using a sequence of observations. This receiver also rejects MAI and estimates channel fadi...
متن کاملCounting solutions for the CDMA multiuser MAP demodulator
We evaluate the average number of locally minimal solutions for maximum-a-posteriori (MAP) demodulation in code-division multiple-access (CDMA) systems. For this purpose, we use a sophisticated method to investigate the ground state properties for the Sherrington-Kirkpatrick-type (i.e. fully connected) spin glasses established by Tanaka and Edwards in 1980. We derive the number of locally minim...
متن کاملCan quantization improve error performance in CDMA?
Abstract A K-user direct-sequence spread-spectrum code-division multiple-access (CDMA) system with (q log2 K)-bit baseband signal quantization at the demodulator is considered. It is shown that additionally quantizing the K + 1 level output signal of the CDMA modulator into q bits improves significantly the average bit-error performance in a non-negligible regime of noise variance, σ 2, and use...
