The present invention provides for making code rate adjustments and modulation type adjustments in a pseudonoise (PN) encoded CDMA system. Coding rate adjustments may be made by changing the number of information bits per symbol, or Forward Error Code (FEC) coding rate.

In signal detection system and method implemented to reduce the effects of interference in multi-user detection systems, a receiver defines a frame of symbols containing at least one window based upon a number of user signals contained in a received signal r(t). A symbol amplitude of a single-user in the multi-user system is approximated over the window of the frame based on a number of reflected signal paths of the received user signal. A perturbative correction value is calculated based upon a correlation matrix. An estimation of the symbol amplitude of the single-user signal is calculated over one or a number of windows of the frame. The single-user signal is detected when the symbol amplitudes of the entire signal within the frame has been calculated. To reduce the number of interfering users in a multicell CDMA system, the symbol codes are modified to include an even code and an odd code. The even and odd codes are symmetrically separated over the duration of the symbol to form an interference reduction window. If the delay offsets of the symbol codes are less than the interference reduction window and the even codes are assigned to a first cell, and odd codes to adjacent cells, then the adjacent cell interference vanishes.

A railway vital or critical application system substitutes commercial off-the-shelf (COTS) hardware and / or software for railway-domain specific product components, yet is validated to conform with railway vital system failure-free standards. The vital system uses a pair of COTS personal computers and operating systems with asymmetric communications capability. Each computer and operating system may differ for additional redundancy.

The first computer has sole capability to send vital system output messages including the output data and an output security code, but only the second computer has the capability of generating the output security code. A failure of either computer's hardware, software or processing capability results failure to transmit a vital system output message or an output message that cannot be verified by other vital systems.
