Description: This program demonstrates a half-duplex 9600-baud UART using // Timer_A3 using no XTAL and an external resistor for DCO ROSC. DCO used for // TACLK UART baud generation. The program will wait in LPM4, echoing back // a received character using 8N1 protocol. On valid RX character, the // character is echoed back. // Using a 100k resistor on ROSC, with default DCO setting, set DCOCLK ~ 2MHz. // ACLK = n/a, MCLK = SMCLK ~2MHz DCOCLK

文件來源： 我的畢設(shè) 仿真結(jié)果： 在窄帶Rayleigh快衰落信道下幾種檢測方法的誤碼率性能比較 說 明： 參數(shù)tx，rx,L，EbN0可以根據(jù)需要更改。 tx，rx是收發(fā)天線數(shù)，根據(jù)需要取值就好了，一般研究2發(fā)2收和4發(fā)4收 EbN0是信噪比取值范圍，根據(jù)需要選擇吧。取得點(diǎn)多當(dāng)然算得慢。 L影響結(jié)果的波動性和誤碼率所能達(dá)到的下限，L值取得越大圖像越接近真實(shí)情況。如果 EbN0最大值有20dB那么誤碼率可以達(dá)到10負(fù)4次方建議L不低于10000。 使用方法： 把db.m和minnorm.m存進(jìn)任意文件夾，然后打開matlab，F(xiàn)ile->Set Path->Add Folder加入 文件夾。在matlab中輸入命令db即可

Very simple USB 1.1 PHY. Includes all the goodies: serial/parallel conversion, bit stuffing/unstuffing, NRZI encoding decoding. Uses a simplified UTMI interface. Currently doesn t do any error checking in the RX section [should probably check for bit unstuffing errors]. Otherwise complete and fully functional. There is currently no test bench available. This core is very simple and is proven in hardware. I see no point of writing a test bench at this time.

This file is distributed in the hope that it will be useful, but WITHOUT WARRANTY OF ANY KIND. Author(s): Ole Saether DESCRIPTION: This example should be used together with ex2a-tx433.asm. One nRF9E5 evaluation board (receiver) should be programmed with the hex-file generated from assembling this file and the other evaluation board (transmitter) programmed with the hex-file generated from assembling ex2a-tx433.asm. All switches on the DIP-swith S206 on the receiver must be set to the "on" position and all switches on the DIP-swith S205 on the transmitter must be set to the "on" position. When one of the switched SW1-SW4 on the transmitter is pressed the corresponding LED on the receiver is turned on. The functionality is the same as in ex2c-rx.c.
