When the radar system detects low-altitude, small, slow-moving (LSS) targets, strong clutter interference from ground will cause false alarms and affect detection performance. In this paper, a phased array transmit beam steering algorithm is proposed to minimize radiation. By minimizing weighted vector norm choosing variable sidelobe levels, pattern can achieve deep notches in ground-related ar...

We rst study the capacity of Nakagami multipath fading (NMF) channels with an average power constraint for three power and rate adaptation policies. We obtain closed-form solutions for NMF channel capacity for each power and rate adaptation strategy. Results show that rate adaptation is the key to increasing link spectral eeciency. We analyze therefore the performance of constant-power variable...

The capacity of deterministic, complex and discrete time memoryless Additive White Gaussian Noise (AWGN) channel under three constraints, namely, channel input average power, channel input amplitude and delivered power at the channel output is considered. The delivered power constraint is modelled as a linear combination of even-moment statistics of the channel input being larger than a thresho...

nowadays, economic load dispatch between generation units with least cost involved is one of the most important issues in utilizing power systems. in this paper, a new method i.e. water cycle algorithm (wca) which is similar to other intelligent algorithm and is based on swarm, is employed in order to solve the economic load dispatch problem between power plants. wca is used to solve complicate...

Given a linear, time-invariant, discrete-time channel , the problem of constructing N input signals of finite length K that maximize minimum 1, distance between pairs of outputs is considered. Two constraints on the input signals are consid-e r e d a power constraint on each of the N inputs (hard constraint) a n d a n average power constraint over the entire set of inputs (soft constraint). The...

In cellular networks, conventional user association algorithms are solely based on downlink (DL) performance, which may lead to inefficient transmission power and high interference in the uplink (UL) transmission. In addition, the backhaul data rate constraint has been neglected by the majority of the existing user association algorithms. However, the backhaul constraint has become more severe ...

In this paper, power adaptation strategies for minimizing bit error rate (BER) subject to an average power constraint for orthogonal space-time coded multiple-input multipleoutput (MIMO) systems with mean and covariance feedback over joint transmit-receive correlated channels are presented. We first develop an optimal spatial-only power control (PC) based on an approximated BER bound, which can...
