对于加性高斯白噪声信道的直接序列扩频多址通信系统，得到了平均差错概率的上下界。根据差错概率函数的凸性属性形成的界限对于最大多址干扰不超过期望信号并且签名序列周期等于数据脉冲的持续时间的系统是有效的。对于具有少量同时活动的发射机的系统，对边界的紧密性进行了检验。这是通过比较几个系统参数值的上下限来实现的。还将这些界限与基于信噪比的近似值和切尔诺夫上界进行了比较。
Upper and lower bounds on the average probability of error are obtained for direct-sequence spread-spectrum multiple-access communications systems with additive white Gaussian noise channels. The bounds, which are developed from convexity properties of the error probability function, are valid for systems in which the maximum multiple-access interference does not exceed the desired signal and the signature sequence period is equal to the duration of the data pulse. The tightness of the bounds is examined for system with a small number of simultaneously active transmitters. This is accomplished by comparisons of the upper and lower bounds for several values of the system parameters. The bounds are also compared with an approximation based on the signal-to-noise ratio and with the Chernoff upper bound.
