最後闡述了空時碼概念，並詳細給出了空時碼編碼設計思想和準則。 -
According to the types of rock density and magnetism of magmatite, with separation, continuation, derivation, and false color encoding between gravity anomaly and magnetic anomaly as well as a composite process of their attributive information, the magmatite belts reflected by both gravity anomaly and magnetic anomaly can be divided into two belts and seven group sections based on their positions in the tectonic unit, the magma series characteristics, and the time - space relationship with the ore belt
摘要根據不同類型巖漿巖的巖石密度、磁性的不同，通過重磁異常分離、延拓、求導、異常的彩色編碼及重、磁特徵信息的復合處理等，按重磁反映的巖漿巖帶所處的構造單元部位、巖漿系列特徵以及與礦帶的時空關系，將秦嶺造山帶劃分為2帶和7個群段。 -
The parsing time and space is related to the format structure and encoding of a message
解析時間和空間與消息格式（結構和編碼）有關。 -
The essence of efmam is that, without destroying the original am ’ s structure and encoding strategies, the patterns in the original space is mapped into the similarity space, which is spanned by the training patterns, by means of empirical kernel map. thus the double noise tolerance is achieved. one is due to the empirical kernel map and the other due to the auto - fmams
Efmam的實質是在不改變原始fmam結構和編碼策略的前提下，藉助經驗核映射，將原始輸入空間中的模式映射到由訓練模式張成的相似度空間中，從而達到雙重抗噪性（一是由於經驗核映射的引入，二是自聯想fmam本身的抗噪性）的目的。 -
Space - time block codes ( stbc ) based on orthogonal design has attracts enough attentions in its applications in mimo - ofdm systems for its full diversity exploiting and low coding / decoding complexity. these applications include not only system performance improvement, but also reduction of the peak to average power ratio in mimo - ofdm systems. under these backgrounds, this paper first studies space - time block codes under the single carrier, flat fading situation, discusses the encoding / decoding principle and its performance under different channels. then, the author focused on the performance of space - time codes under time selective and frequency selective channels, uncovered the fundamental cause of how maximum doppler shift and power delay profile influences the performance of space - time codes through deduction and simulation
在上述背景下，本文以單載波，平坦衰落通道下的空時分組碼為切入點，深入分析了其編譯碼原理和在不同通道情況下的性能;以此為基礎，後文展開了對空時分組碼在多載波，時間選擇性和頻率選擇性衰落通道下的性能研究，通過理論推導和充分的模擬，揭示了空時/頻分組碼在時頻選擇性衰落通道中的性能變化的根本原因;在以上對多載波系統中空時分組碼的研究的過程中，作者發現了空時分組碼在降低系統峰平比方面應用的可行性，提出了一種降低峰平比的新方法。
