Techniques for Incoherent Scatter Communication

Special radiometric-detection procedures are appropriate when communication signals are severely distorted by a rapidly fluctuating, noisy, time-dispersive channel. This paper presents a performance analysis of some digital communication techniques that can be used when most other techniques fail. Error-probability expressions are derived and evaluated for a wide range of possible operating conditions. Effective use of available signal power is found to be possible on badly behaved channels, provided there is sufficient bandwidth available for the optimization of performance.
