Abstract :
The design of a portable, short range, conferencing direct sequence spread spectrum radio for applications in both specialized and commercial communications is presented. The design aims for simplicity to achieve low cost. Conferencing is achieved through packetisation of digitised speech which allows time division multiple access. There is no time slot allocation scheme but collision avoidance of the packets is achieved through sensing of incoming packets. Direct sequence spread spectrum is used to enhance system robustness and to cater for future implementation of CDMA
