The disclosure relates to a pulse amplitude modulation (PAM) data encoding technique capable of reducing effects due to supply noise. A data transmission method according to an embodiment includes identifying an encoding rule of mapping a plurality of pieces of N-bit data and M data symbols, according to a designated level, obtaining a plurality of segmented pieces of data by performing segmentation on input data in units of N bits, mapping the obtained plurality of segmented pieces of data to the M data symbols based on the identified encoding rule, and transmitting the M data symbols obtained as a result of mapping through a plurality of single-ended data lines, wherein an absolute value of a sum of the M data symbols has a value equal to or less than the designated level.

A method for wireless communication includes allocating a transmission bandwidth for transmission to a user equipment (UE). The method further includes determining if the allocated transmission bandwidth is less than or equal to a maximum estimated BW.sub.DPD. The maximum estimated BW.sub.DPD is the maximum estimated signal bandwidth that a transmitter is configured to digitally pre-distort. The method also includes digitally pre-distorting transmit signals and transmitting the digitally pre-distorted transmit signals to the UE if the allocated transmission bandwidth is less than or equal to the maximum estimated BW.sub.DPD. The method also includes transmitting to the UE without digitally pre-distorting the signals if the allocated transmission bandwidth is not less than or equal to the maximum estimated BW.sub.DPD. The method also includes applying digital crest factor reduction to the transmit signals if the allocated transmission bandwidth is less than or equal to the maximum estimated BW.sub.CFR.

A method for estimation of a network path segment delay includes determining a scaled time stamp for each packet of a plurality of packets by scaling a time stamp for each respective packet to minimize a difference of at least one of a frequency and a frequency drift between a transport protocol clock of a host and a monitoring point. The time stamp for each packet is provided by the transport protocol clock of the host. A corrected time stamp for each packet is determined by removing from the scaled time stamp for each respective packet, a temporal offset between the transport protocol clock and the monitoring clock by minimizing a temporal delay variation of the plurality of packets traversing a segment between the host and the monitoring point.

Systems and methods are directed to phase modulation of polar coordinates in a transmitter of wireless signals, to achieve high transmit power levels while meeting spectral mask and EVM requirements. An input signal is mapped to a sequence of modulation frequency (e.g., O-QPSK to MSK) to generate a mapped signal. A digital frequency shaping filter is applied to the mapped signal to generate a shaped signal. An adaptive rounding algorithm is applied to the shaped signal to generate a reduced bit-width signal. A digital frequency synthesizer is applied to the reduced bit-width signal to generate an analog waveform for transmission.

The server further includes a waveform verification module. The waveform verification module is configured to analyze the custom waveform based on the at least one signal parameter, thereby generating waveform analysis data. The waveform verification module is configured to forward the waveform analysis data to the at least one client. Further, a method for providing a signal including a custom waveform is described.
