Abstract： |
The invention is concerned with the space protection filling method of the training sequence for the single or multi-carrier wave radio communication system with multi-pathway interference. It is to achieve compatible of the single-single carrier wave modulating system of the BAP sequence and the PN sequence. The definition of the new training sequence is the Binary All Pass, BAP. Its average peak ratio closes to the least BAP sequence because its anti-dispersing Transformee de Fourier is the PN sequence. The BAP sequence is with invariableness frequency domain, like low average peak ratio and so on. |
