Hi, i'm Pourya Alinezhad.

Telecommunication Roadmap and Network solution specialist- (looking for a PhD opportunity)


I am working as “Technology Roadmap and Network Solutions” engineer at MCI. I have been working on product/ technology’s strategy, vendors’ qualification, envisioning road-map and evolution to next generation technologies. At this job we are investigating E2E 5G standards and work on testbeds to initialize moving towards 5G in Iran. I have two years of work experience as a BSS engineer at HUAWEI where I could participate at integration and swap of BSC/RNC/OSSs and also BTS/NB/eNBs.

My Education background includes M.Sc. in Telecommunications and BSc of Electronics engineering and a recent one year MBA certificate.My research interests focus on digital signal processing, phased arrays and radar signal processing known as Statistical Signal Processing, the subject treats signals as stochastic processes, utilizing their statistical properties to perform signal processing tasks in a manner to raise performance of computational procedures or to eliminate undesired impinging signals from partial measurements.

Before joining Telecom industry I was a freelancer Electronic engineer with dense background in Programming and Electronics softwares and R&D experience on Digital signal processing and FPGA/ARM processors.

Broadband Adaptive Beamforming of Conformal Arrays for Wireless Communications Based on Generalized Sidelobe Canceller

• Pourya Alinezhad, Saeid R.Seydnejad .: ' Wireless Personal Communications,September 2017, Volume 96, Issue 1, pp 1131–1143

Conformal arrays are increasingly used in recent wireless communication systems due to their flexibility in mounting on arbitrary surfaces. Many of such systems require working with broadband signals. However, designing conformal arrays has been limited mostly to pattern synthesis techniques due to the complexity imposed by the different contribution of individual antenna patterns to the overall array response. Such pattern synthesis techniques greatly confine the application of the beamformer in dynamic environments since they are fundamentally non-adaptive data independent methods. In this article, the conventional space–time broadband generalized sidelobe canceller (GSC) is used to develop an adaptive method for an arbitrarily-shaped conformal array. The constraint matrix assumed for the main beam of the conventional GSC structure is modified to incorporate the pattern of each individual element. This treatment allows the element responses to be directly involved in the weight adjustment algorithm and contribute to the array overall response without having any additional complexity. The proposed method can handle different types of the constraints, although the analysis presented here is based on the angle–frequency domain constraints which nevertheless eliminates the presence of the pre-steering delays and ensures a frequency invariant beampatterm required for wideband beamforming. The simulation results which are presented for a typical cylindrical array show that the proposed method can create the desired broadband beampattern with high performance and in an adaptive manner.

DOA estimation in conformal arrays based on the nested array principles

• Pourya Alinezhad, Saeid R.Seydnejad, Dariush Abbasi-Moghadam .: 'Digital Signal Processing, Volume 50, March 2016, Pages 191-202

The nested array structure has attracted great attention recently due to its ability in reducing the number of sensors in an array and at the same time preserving the array performance. While a uniform linear array (ULA) can detect at most N-1 sources with N sensors, a nested array can provide O(N^2) degrees of freedom with the same number of sensors; allowing us to detect K sources with N sensors. Direction of arrival (DOA) estimation in a conformal array is a challenging task. In this article, by breaking the conformal array into smaller sub-arrays and using an interpolation technique, we employ the nested array principles to detect more number of sources than sensors. This comes at the cost of more snapshots and lower resolution, in the DOA estimation of an arbitrarily-shaped conformal array. Each sub-array in the conformal array is selected such that the “shadow effect” which leads to an incomplete steering vector in the DOA estimation algorithm is eliminated. The selected sub-arrays are then transformed to virtual nested arrays where more degrees of freedom can be obtained by applying the MUSIC algorithm for DOA estimation. The application of our proposed method is highlighted by considering a set of comprehensive examples for cylindrical and spherical arrays.
