This paper addresses the noncoherent detection problem for direct-sequence code-division multiple-access (DS-CDMA) signals in the presence of antenna...

In this paper, we investigate pilot-symbol-aided parameter estimation for orthogonal frequency division multiplexing (OFDM) systems. We first derive a...

A closed form formula is derived for the bit error rate (BER) of orthogonal-frequency-division-multiplexing (OFDM) with M-ary differential-phase-shift...

This paper presents a new frustum ray tracing technique (FRTT) for the prediction of channel characteristic maps in a complex in-building environment....

Determining the best base station to serve a mobile user is a key process in cellular systems. Optimal selection of a serving base station guarantees...
