摘要:

在GSM/EDGE基站,通常配备两个接收天线,以便在噪声和干扰受限的场景应用的合并算法,前者采用MRC算法,后者采用IRC算法。随着小区不断变小容量要求的不断提高,同频干扰成为抑制容量的主要因素。尤其是针对典型城区应用场景,基站需要配备性能增强的干扰消除合并技术,即EIRC。由于其增益相对于IRC来说大幅提高,所以适合IRC,MRC的同步精度就会制约EIRC的使用,另外由于EIRC对时偏较敏感,需要高精度的同步算法,文中提出了针对8PSK PS业务的新同步算法,可以较好地解决这一问题。

Abstract:

The GSM/EDGE base station is usually equipped with two receiving antennas for merging algorithm to be applied in the scenarios of noise and interference-limited applications,MRC algorithm for the former and the IRC algorithm for the latter.With the cell getting ever smaller and requiring greater capacity,the co-channel interference becomes the major factor to inhibit the capacity.Especially in the typical urban scenarios,base stations need to be equipped with the performance enhancements interference cancellation merging technology of EIRC.Due to its substantial increase in gain relative to the IRC,the synchronization accuracy suitable for IRC and MRC will restrict the use of EIRC.The greater sensitivity of EIRC to the time partial requires a high-precision synchronization algorithm.The new synchronization algorithm proposed for 8PSK PS business can solve this problem.
