The processor is configured to interpret, according to a second communications protocol, the pattern of energy levels to decode a block of data represented by the pattern of energy levels. Another embodiment is a method producing index modulation signals of the second communications protocol.Kaushik ...
Hence, it is nothing but digital modulation. As we have already discussed, sampling and quantization are the important factors in this. Delta Modulation gives a better output than PCM. Digital data to Analog signals − The modulation techniques such as Amplitude Shift Keying (ASK), Frequency ...
➨Higher level modulation schemes increases data rate as more number of data bits are mapped on single signal elements. For example QPSK maps 2 bits on single symbol or signal element where as 16-QAM maps 4 bits on single symbol or signal element and so on. ➨It reduces error probabilit...
These methods do not have the autoencoder structure and the output of semantic encoding are binary codewords, then they can be combined with all traditional channel coding methods and classical modulation modes to form separate source and channel semantic coding methods. Also, these methods do not...
to words within specific semantic domains compared to the others. Here SI was defined by the cell’s ability to differentiate words within a particular semantic domain (for example, ‘food’) compared to all others and reflected the degree of modulation. The SI for each neuron was calculated ...
In the right circumstances, however, Manchester encoding can be a valuable asset, particularly when reliability is crucial or when a separate clock signal is not practical. For this reason, Manchester encoding is commonly used inradio frequency identification,near-field communicationandinfraredprotocols....

In a case where communication channel 152 comprises a magnetic disc and head, codewords 172, 174 will be in the form of serial write currents delivered to a write transducer in the head. With other types of communication channels, modulation can include other known forms of modulation such as...
or other network element. Transmitter2includes LDPC encoder and stream parser4and modulation and mapping function5, in this MIMO configuration. LDPC encoder and stream parser4encodes transmit data stream TX_DATA according to a fixed block size error correcting code; an example of such a code that...
An LDPC code encoding and modulation method and a communications apparatus are provided to resolve a problem of poor transmission performance and low transmission reliability that are caused in an existing modulation method. Under the method, an information bit sequence Sb can be obtained. The Sb ca...
