Introduction to Modulation

Faruque, Saleh

Pages: 1 –15

[Modulation is a technique that changes the characteristics of the carrier frequency in accordance with the input signal. Figure 1.1 shows the conceptual block diagram of a modern wireless communication system, where the modulation block is shown in the inset of the dotted block. As shown in the...

Amplitude Modulation (AM)

Faruque, Saleh

Pages: 17 –32

[In Amplitude Modulation (AM), the amplitude of the carrier changes in accordance with the input analog signal, while the frequency of the carrier remains the same. The modulated carrier contains several spectral components, requiring frequency domain analysis. In an effort to examine this, this...

Frequency Modulation (FM)

Faruque, Saleh

Pages: 33 –44

[In Frequency Modulation (FM), the frequency of the carrier changes in accordance with the input analog signal, while the amplitude of the carrier remains the same. The modulated carrier contains several spectral components, requiring frequency domain analysis. The key concept and the underlying...

Amplitude Shift Keying (ASK)

Faruque, Saleh

Pages: 45 –55

[In amplitude shift keying (ASK), the amplitude of the carrier changes in discrete levels in accordance with the input digital signal, while the frequency of the carrier remains the same. In this chapter, the ASK modulation is presented along with the respective spectrum and bandwidth. These...

Frequency Shift Keying (FSK)

Faruque, Saleh

Pages: 57 –67

[In frequency shift keying (FSK), the frequency of the carrier changes in discrete levels in accordance with the input digital signal, while the amplitude of the carrier remains the same. In this chapter, the FSK modulation will be presented along with the respective spectrum and bandwidth. These...

Phase Shift Keying (PSK)

Faruque, Saleh

Pages: 69 –83

[In phase shift keying (PSK), the phase of the carrier changes in discrete levels in accordance with the input digital signal, while the amplitude of the carrier remains the same. In this chapter, the PSK modulation will be presented, along with the respective spectrum and bandwidth. These...

N-Ary Coded Modulation

Faruque, Saleh

Pages: 85 –104

[This chapter presents a method of multi-level coded modulation where instead of using one code at a time, two or more codes are used simultaneously and then modulated by means of an M-ary modulation scheme. At the receiver, the decoder recovers the data by means of code correlation. This type of...
