AbstractThis paper analyzes the use of a coded multicode spread-spectrum technique to reduce radio power for personal communication devices in indoor video transmission. The performance of indoor video transmission is measured by the outage probability, which is the probability that the instantaneous bit error rate (BER) exceeds an acceptable level. We first derive the outage probability. The result is used to characterize the power reduction. It is found that the amount of power reduction depends on the required BER level. For indoor video transmission, which typically requires a BER of 10-5, a substantial power reduction exceeding 3dB can be obtained. If outer coding is used in order that the BER requirement can be relaxed, results show that it is preferred to maintain the required BER to be less than 10-4 for more-effective utilization of the power-reduction capability.
