The false alarm probability of a novel signal detection approach based on a two-channel interferometer is derived. The normalized detection threshold is computed using the golden section search algorithm.
In this paper two novel methods for using network coding in the cooperative networks have been proposed. In the first scheme, network coding generates some redundancy in addition to the redundancy that is generated by the channel code. These redundancies are used in an iterative decoding system at the destination. In the second scheme, the output of the channel encoder in each source node is shortened...
In this paper a hybrid control system for a novel small scale coaxial helicopter is presented. Based on a cascade architecture the control system is made up of an inner-loop, for attitude control, and an outer-loop, for trajectory control. The inner-loop consists of three PID controllers for the roll and pitch angles, and altitude control. The outer-loop generates the reference signals for the inner-loop...
This paper deals with the sub-carrier and bit allocations for multi-user orthogonal frequency division multiplexing (OFDM) systems by a modified particle swarm optimization (MPSO) method for a specific bit error rate (BER). The resources (subcarriers and the number of bits per symbol per subcarrier) are allocated according to the instantaneous channel state information (CSI) which is assumed to be...
In this paper, we design and implement model independent observer-controller based output feedback method for robot manipulators. The control design uses only proportional and derivative (PD) error terms for trajectory tracking of nonlinear robot manipulators. The unknown velocity signals is generated by the output of the linear observer. The design is very simple in the sense that it does not require...
