摘要

频带的稀缺性成为制约移动通信领域巨大发展的瓶颈。目前，移动通信中普遍采用蜂窝技术来实现频谱效率的最大化。由于频率复用，出现了同信道干扰的问题，因此我们必须将频率复用系数限制为7。我们使用栅格编码调制在信号空间中施加正交性，因此我们已经能够在4的频率重用因子下实现令人满意的CCI性能，从而使频谱效率大约翻倍。对系统进行了性能分析。通过仿真验证了理论预测。

BER analysis of a set of TCM schemes for reducing cochannel interference in cellular mobile communication

Scarcity of the frequency band is acting as a bottleneck to the tremendous advancement in the field of mobile communication. Nowadays cellular technology is being invariably employed in mobile communication to maximize the spectral efficiency. Due to the frequency reuse there comes the problem of co-channel interference into the picture, due to which we have to restrict the frequency reuse factor to 7. We have used trellis coded modulation to impose orthogonality in the signal space due to which we have been able to achieve satisfactory performance in terms of CCI at a frequency reuse factor of 4, thus approximately doubling the spectral efficiency. Performance analysis of the system is done. Theoretical predictions are verified through simulations.
