Algoritma kawalan nisbah kuasa puncak-ke-purata (PAR) baru untuk isyarat akses berbilang akses (FC/MH-CDMA) terkawal maklum balas terkawal multitone-hopping code-division. Dalam FC/MH-CDMA, memandangkan setiap cip terdiri daripada nada jamak, penggunaan tenaga yang disebabkan oleh PAR yang besar tidak boleh diabaikan pada pemancar. Algoritma kawalan PAR yang dicadangkan secara berulang membina kod frekuensi masa yang mencapai pratetap, sasaran PAR di bawah syarat bahawa semua isyarat dihantar secara tak segerak. PAR sebanyak 1 dB ditunjukkan boleh dicapai, dan prestasi kadar ralat bit ditunjukkan hanya dipengaruhi sedikit jika sasaran PAR ditetapkan lebih besar daripada 3 dB. Pengaruh kuantisasi juga dibincangkan dari segi aplikasinya kepada saluran maklum balas yang terhad.

Abstract: A novel peak-to-average power ratio (PAR) control algorithm for feedback-controlled multitone-hopping code-division multiple access (FC/MH-CDMA) signals is proposed. In FC/MH-CDMA, since each chip consists of plural tones, the energy consumption due to a large PAR is not negligible at the transmitter. The proposed PAR control algorithm iteratively constructs a time-frequency code that achieves a preset, target PAR under the condition that all signals are asynchronously transmitted. A PAR of 1 dB is shown to be achievable, and the bit-error rate performance is shown to be only slightly influenced if the target PAR is set to be larger than 3 dB. The influence of quantization is also discussed in terms of its application to limited feedback channels.
