This paper discusses the design and implementation of a Digital Pre-Distortion (DPD) system for RF power amplifier (PA) linearisation in an in-house designed Software Defined Radio (SDR) platform. An indirect learning approach using orthogonal memory polynomial model is adopted for the DPD design. Important aspects of the SDR architecture relevant to DPD implementation are outlined. Several techniques...
Heart sounds are obtained by the beating heart and the resultant flow of blood through it (particularly, the turbulence created when the heart valves snap shut). A patient's heart problem is often inferred by the doctor after listening to the heartbeat sound. This technique is known as auscultation.
