Keeping students engaged in the learning process is a challenge faced by most teachers. Instituting a bell schedule that requires them to make changes in their traditional instructional delivery may increase that challenge exponentially. The benefit

A new detection method for data-dependent superimposed training with equi-spaced amplitude modulation or equi-spaced square quadrature amplitude modulation is presented in this study. Symbol and bit error floor of the proposed detection method is ana

In this paper, based on a belief-propagation decoding strategy, a class of generalized parity-check codes called complex rotary codes is investigated. It is shown that, by using iterative sum-product decoding, the complex rotary codes have a much low

A physically based method has been developed to simulate the wideband HF ionospheric propagation channel relevant to the case of wideband spread spectrum HF communications and also other HF applications such as digital broadcasting and over-the-horiz

Phase Modulation schemes have been extensively used in mobile systems. TETRA -1 supports π/4-DQPSK, where as TEDS supports π/8-D8PSK along with QAM schemes in order to achieve higher data rate. In this paper the performance of phase modulation sche

In an application to measure subterranean radio propagation, a wide-band low-frequency channel sounder makes use of a modified pseudo-random binary sequence with an imperfect (non-impulsive) auto-correlation function (ACF). The transmitting antenna f

A novel synchronization technique is described. In this method symbol timing is derived from the received data. This method of synchronization is highly suited to a communication path in which there are a number of modes of propagation, e.g. the HF c

A new adaptive trellis decoding technique for block codes is proposed. The technique is based on an encoding technique which allows the design of almost all known linear codes together with their minimal trellises. The proposed adaptive trellis decod

New classes of multi-level and complex sequences with perfect periodic autocorrelations are presented. The sequences are derived directly from certain M-sequences over rational and Gaussian integers.
