Error rates of orthogonal frequency division multiplexing (OFDM) signals are considered for system using multichannel reception with maximum ratio combining (MRC) receivers in Nakagami-m fading generated by sum of sinusoidal method using Rayleigh and Ricean channel. The paper also discusses the effect of frequency offsets, nakagami-m parameter m on OFDM(More)
Reciprocating magnetic separators are used in the purification of kaolin clay and titanium dioxide. Design parameters and fabrication details are reported for the high temperature superconducting (HTS) coil. The HTS coil is 0.7 m in length and has a 0.5 m inner diameter. The central operating magnetic field is a nominal 3.0 T with a design operating current(More)
