This article describes the super-regenerative receiver (SRR), a device widely used in short distance telemetry and remote control applications. The difficulty in modeling the regenerative behavior served as the basis for “cut and try” methodology based on results obtained from the simplified model using a conventional approach. This work presents the SRR behavior to practical implementations by dynamically controlling the injection-mode levels of the super-regenerative oscillator (SRO) for optimum sensitivity and dynamic ranges.

The Mobile Communications industry is currently developing standards and solutions for the next steps in the evolution of mobile networks. This introduction looks at the fundamental radio and network technologies being introduced in these steps, and how this is aligned into the future Fixed Mobile convergence (FMC) of the Next Generation Networks.

Commercial radio technology has reached an inflection point, similar to the transition from analog to digital, when we invented a whole range of digital technology; now we’re moving from single carrier technologies, where we transmit one digital symbol at a time, to a new paradigm, where we’re potentially transmitting hundreds of symbols simultaneously.
