Performance evaluation of the trial system based on wideband CDMA
This paper outlines the performance evaluation for verification of the wideband CDMA system. The characteristics of the wideband CDMA system (IS-665), which attracts much attention as one of the next generation PCS (personal communication service) systems, were evaluated. These are PCS standards which are aimed, at high-quality voice transmission equivalent to PSTN, radio data transmission and packet radio transmission. The outdoor field trial results are discussed. The field trial was carried out at a carrier frequency of 2 GHz, a transmission output of 29 dBm and by a three-sector system. The area evaluated under the microcell service experiment was within a radius of about 0.5 miles either in an urban or suburban area. As the voice coding method, 32 kbps ADPCM voice coding featuring good transmission characteristics in a poor radio propagation environment was adopted. As a result of characteristic evaluation trials in the actual environment, it has been shown that the wideband CDMA system is a new promising PCS system and is also favorable for FPLMTS and IMT-2000.
