A wireless digital communication device having a pulse shaping network for pulse shaping digital signals before modulation is proposed. The pulse shaping network includes a shift register to which data to be modulated is supplied. The output of the shift register is connected to the control inputs of the switched weighted current sources. Pulse shaping plays a crucial role in spectral shaping in the modern wireless communication to reduce the spectral bandwidth.

In electronics and telecommunications, pulse shaping is the process of changing the waveform of transmitted pulses. Its purpose is to make the transmitted signal better suited to its purpose or the communication channel, typically by limiting the effective bandwidth of the transmission.

Perhaps the most common pulse-shaping filter type used in communication systems is the Raised Cosine or Root Raised Cosine filter. The name comes from the shape of the spectral response, where the transition band of the filter follows a half-cycle of a raised cosine shape. ECE 461: Digital Communication Lecture 8b: Pulse Shaping and Sampling Introduction Information is digital in today’s world but the physical world is still analog. Digital commu-nication entails mapping digital information into electromagnetic energy (voltage waveforms) and transmitting over an appropriate physical medium (over a wire or wireless).

Pulse shaping plays a crucial role in spectral shaping in the modern wireless communication to reduce the spectral bandwidth. Pulse shaping is a spectral processing technique by which fractional out of band power is reduced for low cost, reliable , power and spectrally efficient mobile radio Pulse shaping means choosing a pulse with the desired spectral and orthogonality properties. Note that some digital communications textbooks assume (many times implicitly) a rectangular pulse shape, which is then converted to another pulse shape (using a filter, as in the example in your question). Pulse shaping (i.e., base-band filtering) can vastly improve the behavior of wired or wireless communication links in an electrical system. Therefore, the pulse shaping filter will need to interpolate by at least a factor of two, and is often interpolated significantly higher than this. Using pulse shaped and interpolated I and Q baseband digital signals, digital-to-analog converters create the analog I and Q baseband signals. INTRODUCTION Pulse shaping and equalization is taken into account when the channel is bandlimited to some specified bandwidth of W Hz Under this condition, the channel may be modeled as a linear filter having an equivalent low pass frequency response C (f), that is zero for lfl >W Hz  For pulse shaping process, consider the design of the signal pulse g (t) in a linearly modulated signal … Pulse shaping is a spectral processing technique by which fractional out of band power is reduced for low cost, reliable , power and spectrally efficient mobile radio communication systems.

Outputs of the shift register are connected to control inputs of switched weighted current sources. The switched weighted current sources are summed over an output resistor.

What this means is that, if your pulse shape is p (t) and you're transmitting at rate T s pulses per second, you want mobile communications.

Pulse shaping is performed in the transmit and receive filters of a communication system. The most common class of filters used for pulse shaping are Nyquist filters (1,2,3). Enhanced Pulse Shaping Filters For IEEE 802.11 OFDM WLANs 23 occurs at the 54th sample. At α=1, the SRRC pulse has its main side lobe at the 50th sample whereas that for RC occurs at the 51st sample.
