Phase-Modulated Optical Communication Systems (Springer Science & Business Media, Berlin, 2005).
These techniques increase the spectral efficiency of the coding via concatenating higher-order modulation using PSK or QAM modulations [6]; however, these communication models have phase jumps in their modulated signals.

In band-limited communication system, the modulated signal always run through filter to limit the bandwidth of the signal; however, the hardware resource consumption of filter includes the multipliers, adders, and registers.
To estimate the transmitted sequence of length N optimally in a wireless communication system transmitting modulated symbols though a multipath channel, the cumulative cost function in (4) rclΔ = ∑ t = 1 N Δ t m = ∑ t = 1 N | r t − ∑ l = 0 L − 1 h l s t − l | 2 (15).
Overall, the weight of evidence in animals exposed for extended periods, up to lifetime exposures of 2 years, at a variety of frequencies and modulations, suggests that exposure to modulated RF does not increase risk of tumor development (Elder JA, personal communication; Dasenbrock 2005).
The modulated signal s(t) is transmitted over the communication channel to the receiver where in the chaotic demodulator, the demodulation or division of the modulated signal s(t) with the chaotic signal u(t) is carried out.
The present study was designed to test the hypothesis that 900 MHz electromagnetic fields, modulated according to the global system for mobile communication (GSM), increases the risk of lymphoma incidence in female AKR/J mice.
Its application to a model of renal tubular degeneration has revealed a link between physico-chemical features and signalling components controlling cell communication pathways, which in turn are differentially modulated in response to toxic chemicals.
