此為編譯原理實(shí)驗(yàn)報(bào)告 學(xué)習(xí)消除文法左遞規(guī)算法，了解消除文法左遞規(guī)在語法分析中的作用 內(nèi)含 設(shè)計(jì)算法 目的 源碼 等等.... 算法:消除左遞歸算法為: （1）把文法G的所有非終結(jié)符按任一種順序排列成P1,P2,…Pn 按此順序執(zhí)行 （2）FOR i:=1 TO n DO BEGIN FOR j:=1 DO 把形如Pi→Pjγ的規(guī)則改寫成 Pi→δ1γ δ2γ … δkγ。其中Pj→δ1 δ2 … δk是關(guān)于Pj的所有規(guī)則； 消除關(guān)于Pi規(guī)則的直接左遞歸性 END （3）化簡(jiǎn)由（2）所得的文法。即去除那些從開始符號(hào)出發(fā)永遠(yuǎn)無法到達(dá)的非終結(jié)符的 產(chǎn)生規(guī)則。
This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise.
The packet include:
1) Packet Builder (Viterbi Encoding, Interleaver, PN generation)
2) Modulator (RRC filter)
3) Demodulator (Matched Filter, RAKE receiver)
4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder).
You should run "Simulation.m" function that include all modules.
