The Transmitter
The transmitter is a key element in the design of the transceiver. The transmitter provides a means of sending out the information, over the channel, with the power necessary to provide coverage to the intended receiver. Several types of modulation methods were discussed with their advantages and disadvantages. There are many types of spread spectrum transmitters that provide process gain to reduce the effects of jammers and to allow more efficient use of the spectrum for multiple users. Digital systems have many advantages over analog systems and different techniques were discussed for optimizing the digital data link.
