摘要： A mobile network device or a User Equipment (UE) including a power amplifier, processing circuitry, and a filter can receive a radio frequency (RF) signal and perform a modulation of the RF signal into a modulated RF signal with a pulse-shaping that reduces even harmonic spurs. The pulse-shaping includes a time-domain modulation that comprises a single-carrier or a discrete Fourier transform (DFT) spread orthogonal frequency division multiplexing (DFT-s-OFDM). The pulse-shaping further reduces one or more narrow-band spurs based on an even harmonic distortion.

摘要： An approach is provided to compensate for inter-carrier interference caused by phase noise in a transmitted or received signal. The approach involves causing an estimation of one or more phase noise spectrum taps that cause inter-carrier interference in a received signal. The approach also involves causing an approximation of an instantaneous phase noise spectrum by a low order finite impulse response filter based on the estimated one or more phase noise spectrum taps. The approach additionally involves determining a de-convolution filter having two or more filter coefficients for one or more orthogonal frequency-division multiplexing symbols associated with the received signal. The approach further involves causing the de-convolution filter to be matched to the approximated instantaneous phase noise spectrum. The approach also involves causing the inter-carrier interference caused by phase noise to be compensated for based on a de-convolution procedure that applies the de-convolution filter to the one or more orthogonal frequency-division multiplexing symbols.

摘要： A noise estimation filter for an orthogonal frequency-division multiplexed (OFDM) system can include a filter bank module, a coefficient squaring module, and a summing module. The filter bank module can multiply a unitary vector by an OFDM signal vector to generate scalar products of the OFDM signal vector. The coefficient squaring module can square the scalar products and weight the scalar products to generate a plurality of weighted single estimates. The coefficient squaring module can include a squaring module for squaring the scalar product to generate a plurality of single estimates and a coefficient multiplication module for weighting each of the single estimates with a noise coefficient forming a plurality of weighted single estimates. The summing module can sum the weighted single estimates to generate a noise and interference power estimate.

摘要： In a wireless, OFDM system, phase noise may be mitigated through the use of an interleaver that is designed to distribute coded block bits across subcarriers of multiple OFDM symbols. Doing so decreases the non-stationary properties of the noise. Such an interleaver may be a rectangular interleaver that maps each block to a different subcarrier to create frequency diversity and to a different OFDM symbol, to create time diversity. One exemplary method of interleaving the symbols is to place a first symbol at row X and column Y of the interleaver. The next symbol is placed in row X+1 and column Y+1. The result of such an interleaving process is a great reduction in the block error rate.
摘要翻译：在无线OFDM系统中，可以通过使用被设计为在多个OFDM符号的子载波上分配编码块比特的交织器来减轻相位噪声。这样做会降低噪声的非平稳特性。这样的交织器可以是矩形交织器，其将每个块映射到不同的子载波以产生频率分集和不同的OFDM符号，以产生时间分集。交织符号的一个示例性方法是在交织器的行X和列Y处放置第一符号。下一个符号放在行X + 1和列Y + 1。这种交错处理的结果是块错误率的大大降低。

摘要： A receiver may reduce phase noise in phase-encoded communications signals using symmetrical averaging to estimate phase shift correction. In one embodiment, a receiver, such as a quadrature amplitude modulation receiver may include a decision feedback equalizer and a filter of low complexity to receive a phase modulated incoming signal. Using a combination of phase shift difference estimates prior and subsequent to a decision point for the received symbols, the filter may derive another estimate of the phase shift relative to the estimated phase shift by the equalizer.
