Improved bounds on the peak sidelobe level of binary sequences

Schmidt proved in 2014 that if ε > 0, almost all binary sequences of length n have peak sidelobe level between ( √ 2 − ε)√n log n and ( √ 2 + ε) √ n log n. Because of the small gap between his upper and lower bounds, it is difficult to find improved upper bounds that hold for almost all binary sequences. In this note, we prove that if ε > 0, then almost all binary sequences of length n have pea...

The peak sidelobe level of random binary sequences

Binary sequences with small autocorrelation at nonzero shifts have a wide range of applications in digital communications, including synchronisation and radar. Let Mn be the minimum of M(A) taken over all 2 n binary sequences A of length n. By a parity argument, it is seen that Mn ≥ 1 and it is known that Mn = 1 for n ∈ {2, 3, 4, 5, 7, 11, 13}, which arises from the existence of a Barker sequen...

Multiplicative Mismatched Filters for Optimum Range Sidelobe Suppression in Barker Code Reception

Very efficient sidelobe suppression of Barker codes of length 13 is achieved through the use of a novel mismatched filter. The mismatched filter is comprised of a conventional matched filter cascaded with a computationally efficient filter based on multiplicative expansion. Several constant parameters are introduced in the terms of the expansion and they are optimized to improve the performance...

Control of Peak Sidelobe Level in Adaptive Arrays - Antennas and Propagation, IEEE Transactions on

AbstructAdaptive beamforming techniques are now widely used to reject interference Uammerklutter) signals in radar, communication, and sonar applications. In adaptive arrays using the sample matrix inversion (SMI) algorithm, inadequate estimation of the covariance matrix results in adaptive antenna patterns with high sidelobes and distorted mainbeams. In this paper, a method is proposed to prec...

the impact of attending efl classes on the level of depression of iranian female learners and their attributional complexity

می توان گفت واقعیت چند لایه ا ی کلاس های زبان انگلیسی بسیار حائز اهمیت است، زیرا عواطف و بینش های زبان آموزان تحت تاثیر قرار می گیرد. در پژوهش پیش رو، گفته می شود که دبیران با در پیش گرفتن رویکرد فرا-انسانگرایی ، قادرند در زندگی دانش آموزانشان نقش مهمی را ایفا سازند. بر اساس گفته ی ویلیامز و بردن (2000)، برای کرل راجرز، یکی از بنیان گذاران رویکرد انسانگرایی ، یادگیری بر مبنای تجربه، نوعی از یاد...
