Raymond Pickholtz Oral History
Pickholtz
received his Bachelor’s from City College
(1954?); worked at RCA on color TV receiver
design (1954-57); worked at ITT Laboratories on
spread spectrum radio systems for aerospace
applications (1957-61); returned to graduate
school at Brooklyn Polytechnic (1961-66); taught at
Brooklyn Polytechnic (1966-72); consulted at IBM
starting ca. 1967-68; taught at George
Washington University (1972-). His research
has been in data networking; modems; satellite
communications; spread spectrum; spread
spectrum multiple access/code division multiple
access; fading channels; scattering; frequency
hopping; and developments in digital radio
(Orthogonal Frequency Division Multiplexing).
He also discusses the future of the field and
his involvement in IEEE.
