求翻譯:當CPM信號受多徑衰落影響時,調制器和 ISI信道的記憶性可組合成一個單一的超格,基于這個超格,仍然可采用格型搜索算法進行聯合均衡和解調【】。對已編碼的CPM信號,可以將均衡器和后端信道譯碼器聯合進行迭代接受。然而,當調制和信道記憶長度很大時,超格的狀態數太多,即使不進行均衡迭代,其復雜度也是不可接受的。為此,可以采用一種次優但具有較低復雜度的Turbo均衡接受機,主要思想是把信道均衡、CPM和信道譯碼操作分開,實現均衡器和解調器、解調器和譯碼器之間雙迭代處理。是什么意思?![]() ![]() 當CPM信號受多徑衰落影響時,調制器和 ISI信道的記憶性可組合成一個單一的超格,基于這個超格,仍然可采用格型搜索算法進行聯合均衡和解調【】。對已編碼的CPM信號,可以將均衡器和后端信道譯碼器聯合進行迭代接受。然而,當調制和信道記憶長度很大時,超格的狀態數太多,即使不進行均衡迭代,其復雜度也是不可接受的。為此,可以采用一種次優但具有較低復雜度的Turbo均衡接受機,主要思想是把信道均衡、CPM和信道譯碼操作分開,實現均衡器和解調器、解調器和譯碼器之間雙迭代處理。

When CPM signal to multi-path fading effects, modulation, and * ISI channels can be combined into memory of a single super-grid, based on the grid, you can still use grid-type search algorithm for the balanced and fair elections as soon as possible. In the encoded CPM signals, you can be balanced, a
