Cyclic adaptive receivers for DS-CDMA signals

In a receiver receiving a signal, the signal including data which is at least modulated by a cyclic sequence, a method for operating the receiver, the method including the steps of:

• determining a plurality of sections, each said section including at least one element of said cyclic sequence;
• detecting portions of said signal, which are modulated by each said section,
• jointly processing detected portions of said signal, which are modulated by a selected one of said sections;
• and
• producing a set of receiver parameters for each said sections, said receiver parameters minimizing a predetermined cost function for said selected section.

In a receiver receiving a signal, the signal including data symbols which are at least modulated by a cyclic sequence, a method for operating the receiver, the method including the steps of:

• demodulating said signal, by said cyclic sequence, thereby producing a plurality of received samples;
• determining a plurality of sections, each said section having a length of at least one sample, each said section being demodulated by a predetermined portion of said cyclic sequence;
• detecting portions of said demodulated signal, which are associated with each of said sections;
• jointly processing said detected portions, which are associated by a selected one of said sections;
• and
• producing a set of receiver parameters for each said sections, said receiver parameters minimizing a predetermined cost function for said selected section.

A receiver for detecting a signal, the signal including data which is at least modulated by a cyclic sequence, the receiver comprising:

• a plurality of processing units, each said processing units being associated with a predetermined section of said cyclic sequence, and
• a distributing unit, connected to each said processing units,
• wherein said distributing unit receives said signal, detects portions of said signal, each said portions being associated with one of said predetermined sections,
• wherein said distributing unit provides selected ones of said portions to a selected one of said processing units, wherein both said selected portions and said selected processing unit being associated with a selected one of said predetermined sections, and
• wherein each said processing units processing said selected portions, thereby producing set of receiver parameters, said receiver parameters minimizing a predetermined cost function for said selected predetermined section.

A receiver for detecting a signal, the signal including data which is at least modulated by a cyclic sequence, the receiver comprising:

• a despreading unit, for demodulating said signal by said cyclic sequence, thereby producing a demodulated signal,
• a plurality of processing units, each said processing units being associated with a predetermined section of said cyclic sequence, and
• a distributing unit, connected between said despreading unit and each said processing units,
• wherein said distributing unit receives said demodulated signal, detects portions of said demodulated signal, each said portions being associated with one of said predetermined sections,
• wherein said distributing unit provides selected ones of said portions to a selected one of said processing units, wherein both said selected portions and said selected processing unit being associated with a selected one of said predetermined sections, and
• wherein each said processing units processing said selected portions, thereby producing set of receiver parameters, said receiver parameters minimizing a predetermined cost function for said selected predetermined section.
