Multiuser detector for variable spreading factors

All in user closed, comprising for reduced the operating order of complexity detection and decoding synchronous or a synchronous CDMA sub, wherein with different is factor. The multi-user detecting with a ZF-BLE, MMSE, solve associated detector and disassembling minimum digital operation is accommodating by Cholesky. The system and method of transmission system response matrix's line, represents the individual user the response to an integral system for transmitting response matrix, sides of represents matching filter, receiving data device according responded is set. The invention decomposes the light of Cholesky; the filter in matching, a mathematical operation number of request.
