you take another approach. You may implement this algorithm. whenever you receive a certain message from transeiver '1' to transeiver '2',transeiver '1' is prevented from sending for the following 20ms and transeiver '2' is allowed to send only in this interval. whenever the timer '20ms' is...
1st of all, there would be no interference if the two transmitters are not coherent , having the same frequency, so even if spatially they are close to each other it doesn't matter what does matter is the operating frequency. Yes they would if you make a tdm plan that is no module can transmit...
i suggest that you should use a comparator of reference 0 and threshold 5v so if signal is -7 it will give 0v and if signal is 7v it will give 5v.

This is so easy, what you need is a cell phone. Nokia for example provide at its development website a pdf containing all "at" commands available. what you would do is to connect the cell phone to the computer and install the driver for its modem. once you do so a serial com port is assigned to...
no for sure it isn't the same. the oscillator at the encoder is used as a digital clock and consequently determines the speed of operation of the encoder. modulator and encoader's frequencies aren't really related. The encoder give the baseband data which is modulated by the modulator on a...
yes of course bro, the levels given by the serial xbee pins are ttl with -7 and 7 volts. so what you need to do is to make these levels 0 and 5 volts inorder for the microcontroller to understand that these are uart data.
what are you talking about, that is a total insane. In ups, a50hz modified sine wave signal is generated which is a square wave alternating between -220v and 220v and having one additional voltage level which is zero. The role of the torroid is to shape filter some of the modified sine wave...
they are instruction cycles since the delay functions are made using various instructions and not using timer module, if you need an accurate delay with certain timing you can use the timer module of the pic.
it would be useful if you state what type of interface you are using to transmit between controller and matlab, if it's a standard serial interface, then make sure that the baud rate used by the controller is the same as that you specified in matlab
first of all, you should understand what cyclostationarity stand for. a good reference is the book:
Wireless Communication Systems: From RF Subsystems to 4G Enabling Technologies-ISBN-10: 0521114039, in chapter 18.
Then you would know that some modulations and schemes are cyclostationary in...
