Design and implementation of online mode switching on hybrid software radio platforms

This paper demonstrates the design and implementation of a configurable mode transceiver using software radio platform. The work implements a radio transceiver in which its communication modulation and frequency carrier can be altered while maintaining operation. The designed transceiver switches between amplitude modulation (analog) and differential binary phase shift keying (digital) upon a user request. While it is capable of automatically switching its frequency carrier upon an increase in bit error rate due to degradation of its wireless channel. The transceiver combines the signal processing modules to perform a configurable multimode radio. The design of the transceiver is implemented using a small form factor software defined radio (SDR).
