摘要：
Interference between multiple users operating under multiuser diversity within a coherence bandwidth in an OFDMA system is reduced by spreading out the users' transmission symbols randomly in time within the coherence bandwidth. When transmission symbols are randomly dispersed, the variance of interference between users in the same sub-band is reduced on average.
摘要（中）：
通过在相干带宽内随时随地扩散用户的传输符号，减少在OFDMA系统中的相干带宽内在多用户分集下操作的多个用户之间的干扰。 当传输符号随机分散时，相同子带内的用户之间的干扰差异平均减小。
