The paper discusses the simulation, design, and test of software-defined radios (SDRs), initially using a legacy 16QAM waveform, followed by a new SDR waveform -orthogonal frequency division multiple access (OFDMA). The SDR system’s error vector magnitude (EVM) is first analyzed and its performance is compared with the legacy waveform results. The implementation also includes the […]

For a still youthful engineer whose curriculum vitae already took in some ill-fated early-days video card work at Apple and the short-lived 3DO games console, Baker could have been […]
