In this paper, we apply General Order Statistics (GOS) theorem to multi-antenna (MIMO) dual-hop amplify-forward fixed-gain cooperative relay network. General order link, unlike the best one, is selected for the transmission/receiving at each hop. The

We present the analysis and design of a FIR filter with balanced ternary coefficients (i.e., −1, 0, +1) suitable for FPGA implementation. The ternary filter taps were generated using a ΣδM process in MATLAB® and the filter implemented in VHDL. A

The clipping and filtering method is analyzed in terms of power savings. The analysis takes account of the gain in the amplifier efficiency due to peak-to-average-power-ratio (PAPR) reduction. Assuming a linear amplifier and a typical digital signal

Sigma-delta modulators are inherently non-linear structures and suffer from many intriguing and unresolved problems. Two approaches are utilized to analyze these structures: analytical and nonlinear approximation techniques. According to the nonlinea

Two structures for single-bit digital comb filtering are proposed. The first structure is based on ternary filtering, however, the output of the filter is in single-bit format. The second structure is based on second-order sigma-delta modulation (Sig

We propose an optimum transmitting structure consisting of adaptive modulation, space-time block coding (STBC), and transmitter beamforming for orthogonal frequency division multiplexing (OFDM) systems to improve the data throughput and error perform

In this work we analyze the performance of the newly proposed digital tanlock loop in the presence of additive Gaussian noise. It is shown that the expected value of the steady-state phase errors at the input and the output of the phase error detecto
