Rat T cells and thymocytes were induced to proliferate by a pair of mAbs, MRC OX-54 and MRC OX-55, directed against rat CD2. Accessory cells were required but their role was not simply for crosslinking of the two mAbs, as neither MRC OX-54 nor MRC OX-55 alone, in the presence of a crosslinking second antibody, caused T cell mitogenesis. Nor could the phorbol ester PMA replace either antibody. T...

In this paper we propose an enhanced maximal ratio combining (MRC) scheme for RAKE receivers in mobile CDMA terminals. It is based on the original MRC scheme derived by Brennan, where the RAKE finger noise powers are used in the combining weights. This enhanced scheme performs nearly as well as Brennan's original MRC scheme, but unlike Brennan’s method, it does not require the estimation of the...

A performance analysis of two hybrid selective combining/maximal ratio combining (SC/MRC) diversity receivers over Nakagami-m fading channels with a flat multipath intensity profile is presented and numerically compared with that of the conventional SC and MRC schemes. Numerical results for particular cases of interest show that the bit error rate (BER) degradation arising from the use of hybri...
