Description: 21IC精华帖之 单片机优化设计
原文片断：
单片机程序的设计、仿真调试只是单片机系统的设计一部分，单片机系统的优化设计才是单片机系统的设计的核心和难点。由于很多人没有认识到这个问题，导致了单片机系统不能工作、或是工作不稳定、成本过高等问题。

Description: This document describes a MATLAB implementation of the 3GPP Spatial Channel Model (SCM) [3GPP03]. The accompanying MATLAB code implements the system level channel model described in Section 5 of [3GPP03], except the “far scatterer clusters” feature from Section 5.5.2 and the intercell interference feature from Section 5.7. These features were left out of the implementation because they make certain restricting assumptions about the network layout. The current implementation has no built-in assumptions on network geometry and is hence usable for a variety of simulation purposes. Platform: |

Description: Inter modulation (SM), as a novel multi antenna transmission scheme, creates a mapping relationship between input bits and transmit antenna ordinal numbers, which is used to carry certain transmission information. However, the scheme maps the sending bits to a uniform distribution signal constellation through a single layer modulation mode, which greatly limits the performance of the system. Hierarchical map coding (SCM) technology is applied to constellation point mapping, which satisfies different quality of service (QoS) requirements of different data services on the same transmission slot, and effectively improves system performance. Based on the principle of SCM, a low complexity detection algorithm is proposed. The simulation results show that the detection performance of the new algorithm is approximate to the maximum likelihood (ML), and the complexity of the receiver increases linearly with the modulation order.
