摘要: For uplink time synchronization and power adjustment, ranging process has been suggested for OFDMA (Orthogonal Frequency Division Multiple Access) based BWA (Broadband Wireless networks like IEEE 802.16. The CDMA (Code type code transmission in contention channel provisioned to send the request by an SS (Subscriber Station) BS (Base Station). In channel, suffers with collision if same is transmitted two or more than subscriber stations a frame. However, number of available codes, applied resolution scheme, SSs network determine probability any arbitrary Since analysis codes one important issues when modeling configuring parameters, this paper, we have mathematically analyzed that issue. A analytical model along simulation results presented analyze terms users, varying window size.
