Ocdma thesis

In such way the total number of code words will be. The Reed Solomon codes are generated using a Galois field. This will introduce unwanted signals that would cause interference and impair the orthogonality of the transmission.

The spot rate of each channel is Mbps STM It is also necessary to have the best quality of signal.

One of the main advantages of OFDM is that is more resistant to frequency selective fading than single carrier systems because it divides the overall channel into multiple narrowband signals that are affected individually as flat fading sub-channels.

Due to their simple geometry and small form factor, high-Q microring resonators are ideally suited for very large scale integration with CMOS microelectronics. In order to satisfy this 3. Incoherent sensing has a less hardware complexness compared to coherent sensing because it does non necessitate stage synchronism.

The OL function is defined by 8: The expression of the error probability of the CR receiver with optical limiter is given by 10 [10]: Sensitive to carrier offset and drift: The combination of high data capacity, high spectral efficiency, and its resilience to interference as a result of multi-path effects means that it is ideal for the high data applications that have become a major factor in today's communications scene.

Another disadvantage of OFDM is that is sensitive to carrier frequency offset and drift. Whereas for AND minus technique as shown in Figure 3, merely two filters are needed for decipherer 1.

The standard signal in Receiver is divided into two complementary subdivisions of spectral french friess. This can be done because the error correction code is transmitted in a different part of the signal. This ensures that the data is only sampled when the signal is stable and no new delayed signals arrive that would alter the timing and phase of the signal.

The encoding and decoding of Reed Solomon codes is done in finite Galois field.
