This thesis presents a new technique for low power biomedical telemetry transmission using direct sequence spread spectrum communications. This technique differs from other spread spectrum systems by using a different frequency range for transmission, by dissipating less power in the transmission of the spread spectrum signal, and in the circuit technique used to generate the spreading code sequence. An experimental transmitter is designed and constructed using these different techniques to create a code division multiple accessing low power biomedical telemetry transmitter. Performance data is collected on the transmitter and receiver simulation is done to verify performance. Comparison of the designed transmitter is then done to other related transmitters in both performance and design.
