一、引言频谱缺乏始终是移动通讯发展的最突出障碍,迄今为止,频谱缺乏是通过缩减带宽和无线信道的复用来解决的,目前看来,这些解决办法已到了极限,必须研究一种新的解决办法迎合发展的需要(当然,这仍然属于提高频谱利用率问题)。
I. INTRODUCTION The lack of spectrum has always been the most prominent obstacle to the development of mobile communications. To date, the lack of spectrum has been solved by reducing the bandwidth and multiplexing of wireless channels. At present, these solutions have come to the limit and a new Solution to the needs of development (of course, this still belongs to the issue of improving spectrum utilization).
