摘要： Collisions between messages simultaneously transmitted by multiple spread-spectrum transmitters are reduced by distributing the transmissions over the available resources of the receiver. The transmitters may be mobile stations and the receiver may be a base station in a CDMA cellular telephone system. Each mobile station uses one or more randomization methods to distribute its transmissions. In the first randomization, the mobile station time- delays its transmissions by a number of chips of the PN code with which it spreads the transmitted signal. A hash function produces the number from an identification number uniquely associated with that mobile station. In a second randomization, the mobile station randomly selects the PN code. In a third randomization, the mobile station inserts a random delay between successive message transmissions or probes if it does not receive an acknowledgement after a predetermined timeout period. A predetermined number of such transmissions is called a probe sequence. In a fourth randomization, the mobile station inserts a relatively long random delay between successive probe sequences if it does not receive an acknowledgement of any probe in the sequence. The noise level is reduced by minimizing transmission power. The mobile station increments the power of successive probes within each probe sequence. The first probe of each probe sequence is transmitted at a predetermined level.

摘要翻译：通过在接收机的可用资源上分配传输来减少由多个扩频发射机同时发射的消息之间的冲突。发射机可以是移动台，接收机可以是CDMA蜂窝电话系统中的基站。每个移动台使用一种或多种随机化方法来分配其传输。在第一次随机化过程中，移动台通过PN码的多个码片对其传输进行时间延迟，利用该码片扩展传输的信号。散列函数根据与该移动台唯一关联的标识号码生成号码。在第二次随机化中，移动台随机选择PN码。在第三次随机化中，如果移动台在预定的超时时间段之后没有接收到确认，则在连续的消息传输或探测之间插入随机延迟。预定数量的这种传输被称为探测序列。在第四次随机化中，如果移动台未接收到序列中任何探测的确认，则在连续探测序列之间插入相对长的随机延迟。通过最小化传输功率来降低噪声水平。移动台增加每个探测序列内连续探测的功率。每个探针序列的第一个探针以预定的水平传送。
