We simulate uncoded BER of BPSK modulated data as a function of SNR -in an AWGN channel -in a Rayleigh fading channel -in an AWGN channel when direct sequence spreading is used and compare results to the theoretical ones. We assume coherent receiver and perfect synchronization.

This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate is equal to chip rate and the output is at symbol rate. Two rates are related by PG, processing gain

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.

顯示ARP緩存信息.A R P高效運行的關鍵是由于每個主機上都有一個A R P高速緩存。這個高速緩存存放了最 近I n t e r n e t地址到硬件地址之間的映射記錄。高速緩存中每一項的生存時間一般為2 0分鐘,起 始時間從被創建時開始算起。
