Reka bentuk sistem komunikasi wayarles dengan kadar penghantaran 6 dan 10 Mbit/s dipersembahkan untuk jalur ISM Jepun 2.4 GHz, di mana teknik spektrum sebaran bernama "CFO-SS (Spektrum Penyebaran Frekuensi Pembawa Offset-Spread)" digunakan. Dalam sistem CFO-SS, kod PN tunggal lazimnya diberikan kepada semua pembawa berganda yang disegerakkan, dan pemisahan frekuensi antara pembawa ditentukan oleh kadar penghantaran setiap pembawa. Untuk merealisasikan sistem CFO-SS, pemerolehan masa dan skim penjejakan, bahagian penting dalam reka bentuk, dibentangkan terlebih dahulu. Seterusnya, prestasi ralat bit dan paket disiasat di bawah persekitaran berbilang laluan yang teruk dengan/tanpa penerima RAKE. Degradasi oleh had lebar jalur saluran, ketidaktepatan kekerapan perkakasan dan gangguan saluran bersama (CCI) juga disiasat oleh simulasi komputer. Keputusan simulasi dipersembahkan mengesahkan prestasi sistem CFO-SS yang mencukupi untuk sistem LAN wayarles menggunakan jalur ISM 2.4 GHz.

Abstract: Design of wireless communications systems with a transmission rate of 6 and 10 Mbit/s is presented for the 2.4 GHz Japanese ISM band, in which a spread spectrum technique named "CFO-SS (Carrier Frequency Offset-Spread Spectrum)" scheme is employed. In the CFO-SS system, a single PN code is commonly assigned to all the synchronized multiplexed carriers, and the frequency separation between carriers is determined by the transmission rate of each carrier. To realize the CFO-SS system, a timing acquisition and tracking scheme, an important part of the design, is presented first. Next, bit and packet error performance is investigated under severe multipath environments with/without a RAKE receiver. Degradation by channel bandwidth limitations, frequency inaccuracy of the hardware and co-channel interference (CCI) is also investigated by computer simulation. Simulation results presented confirmed sufficient performance of the CFO-SS system for wireless LAN systems using the 2.4 GHz ISM band.
