CDMA subtractive demodulation

摘要: Subtractive CDMA demodulation optimally decodes a coded information signal embedded in many other overlapping signals making up received, composite signal. A radio receiver correlates unique code corresponding to the desired be decoded with Moreover, after each is successfully decoded, it recoded and removed from enhanced by decoding order of strongest weakest strength. The individual are spread using block error correction codes which correlated Fast Walsh transforms. Correlated identified as largest transform component remaining reformulated an inverted transform. Any residual or interference caused during extraction recorrelating index that component.
